Table \(\PageIndex{1}\) summarizes the geometries and bond angles predicted for nearest-neighborbonded groups on central atoms with a mixture of lone pairs and bonded groups. There are five electron groups about the central atom in I3, two bonding pairs and three lone pairs. Hence, the Lewis structure of iodine trichloride would be: We can observe that every chlorine atom is surrounded by eight electrons but a central atom, iodine, is surrounded by ten electrons. Here are a few explanations that I have in mind. 4. Save my name, email, and website in this browser for the next time I comment. Structure (b), with fewer LPBP repulsions at 90 than (a), is lower in energy. The iodine atom in $\ce{ICl2}$ is what is termed hypercoordinated (or hypervalent). The point was earned in part (b)(ii) because the answer is consistent with the incorrect Lewis structure drawn in part (a). For ICl2+, we have 20 valence electrons and the central atom iodine has 2 lone pairs and 2 shared pairs. 3. In the VSEPR model, the molecule or polyatomic ion is given an AXmEn designation, where A is the central atom, X is a bonded atom, E is a nonbonding valence electron group (usually a lone pair of electrons), and m and n are integers. They are more reactive than individual halogen atoms from which they are formed. Your email address will not be published. The three atom, iodine and two chlorine are oriented in a straight line keeping the three lone pair in three equatorial position. Iodine trichloride or ICl3 is a bright yellow colored interhalogen compound consisting with one iodine atom and three chlorine atoms. ICl3, named Iodine Trichloride, is an Interhalogen compound. Nonbonding electrons on each of the chlorine atoms (Cl) = 7 1 = 6 or three lone pairs. Compared to a bond order of for I C l X 2 X this means a shorter bond length. For a chemical bond to be a polar covalent bond, the electronegativity difference between two atoms should be between 0.4-1.7. Hybridization is introduced in chemistry as the mixing of two atomic orbitals having similar energies, size and symmetry. The reason behind this reactivity is that the I-Cl bond is weaker due to electronegativity difference between iodine and chlorine. All LPBP interactions are equivalent, so we do not expect a deviation from an ideal 180 in the FXeF bond angle. The hybridization of the central atom can be sp, sp2, sp3, sp3d, dsp2, and sp3d2 depending upon the number and presence of similar energy atomic orbitals. According to the lewis theory, every atom prefers to have eight electrons around itself in the valence shell except Helium and Hydrogen. If we place the lone pair within the equatorial position, we now have three LPBP repulsions at 90. So, 4 electrons (22) and 2 electrons (21) are involved in bond formation for iodine and chlorine atom respectively. ICl5 molecular structure and bond angle? If the isolated pair is in the axial place, the structure turns into a pyramid based mostly on a sq.. If both are in the equatorial positions, we have four LPBP repulsions at 90. The electron geometry for the. (Steric number = 4) In the case that there are four electron groups around a central atom, those groups will lie approximately 109.5 from one another in space. A combination of VSEPR and a bonding model, such as Lewis electron structures, is necessary to understand the presence of multiple bonds. Thus, the total number of valance shell electron becomes eight which matches with the nearest noble gas (Ne) electron configuration (2s2 2p6) in periodic table. ICl 4-Example \(\PageIndex{1}\): Lets try determining the geometric structures of H 2 O and CO 2. There are five groups around sulfur, four bonding pairs and one lone pair. As a consequence there will be less electron-electron repulsion and only the bonding molecular orbital is occupied, because of this we would expect shorter bond lengths in $\ce{ICl2^{+}}$ compared to $\ce{ICl2}$. Steric number of ICl2- = (Number of bonded atoms to iodine + Lone pair on iodine central atom). The electron geometry for the Iodine dichloride anion is also provided.The ideal bond angle for the Iodine dichloride anion is 180 since it has a Linear molecular geometry. Part (b)(iii) is not attempted. Place remaining valence electrons starting from outer atom first. The valance shell electron configuration of chlorine and iodine are 3s2 3p5 and 5s2 5p5 respectively. VSEPR theory or chart says, if the central atom of any molecule is attached with two bonded atoms and contains a total of three lone pairs then the molecular shape of that molecule is linear, and electron geometry is trigonal bipyramidal in nature. 2. This will be determined by the number of atoms and lone pairs attached to the central atom.If you are trying to find the electron geometry for ICl2 - we would expect it to be Trigonal bipryamidal.Helpful Resources: How to Draw Lewis Structures: https://youtu.be/1ZlnzyHahvo Molecular Geometry and VSEPR Explained: https://youtu.be/Moj85zwdULg Molecular Geo App: https://phet.colorado.edu/sims/html/molecule-shapes/latest/molecule-shapes_en.htmlGet more chemistry help at http://www.breslyn.orgDrawing/writing done in InkScape. Use MathJax to format equations. It is one of the exceptions of the octet rule, i.e., the elements of the third period or beyond the third period of the periodic table have 3d electrons for bonding. C From B we designate SnCl2 as AX2E. PDF Chapter 10: Chemical Bonding II: Molecular Geometry and - Prexams providing 8 valence electrons in the outer shell of each chlorine atom. These electrons are called nonbonding electrons and the electron pairs are known as lone pair. This is because the iodine atom is below period two on the periodic table and has access to the d-orbital, hence when it becomes necessary, the iodine atom can open its extra d-orbital and attains more than 8 electrons to complete the octet. This can be described as a trigonal bipyramid with three equatorial vertices missing. However, we predict a deviation in bond angles because of the presence of the two lone pairs of electrons. With two hydrogen atoms and two lone pairs of electrons, the structure has significant lone pair interactions. So starting off by drawing the Lewis structure: . From this we can describe the molecular geometry. We designate SF4 as AX4E; it has a total of five electron pairs. 4, ICl 4 , and ICl 4 +. In the case of the ICl2- molecule, both iodine and chlorine atoms belong to the same periodic group but the electronegativity of an element decrease as we down the group. Hybridization helps to find out the bond angle in any molecule. C All electron groups are bonding pairs, so PF5 is designated as AX5. These compounds are generally written as ABn where n= 1, 3, 5, and 7; A and B are less electronegative and more electronegative elements, respectively. Its in the linked paper, table 1, saying. Therefore, the hybridization of iodine in iodine trichloride is sp3d with trigonal bipyramidal geometry. Unfortunately Im not in a group that does calculations any more. The molecule has three atoms in a airplane in equatorial positions and two atoms above and under the airplane in axial positions. The steric number of iodine central atom in the ICl2- the molecule is 5, thus, it forms Sp. Total number of the valence electrons in chlorine atom = 7, Total number of the valence electrons in iodine atom = 7, Total number of valence electron available for ICl2- lewis structure = 7 + 7(2) + 1 = 22 valence electrons [ICl2- molecule has one iodine and two chlorine atom with one negative charge ion], 2. 4. The ions charge, which is located mostly on the iodine (electronegativity!) Since both iodine and chlorine atom belongs to the same periodic group(Group 17), they have same valence electrons. What are the expected bond angles of ICl4+? The overall dipole moment will be the vector addition of three dipole moments of the Cl-I bond. How is the charge of covalently bonded atoms determined? Octet rule is one of the most significant rule in chemistry as it says that any atom should have eight electrons in its valance shell to match the electron configuration with its nearest noble gas. In ICl2, electrons are shared between iodine and two chlorine atoms. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Determination of hybridization of central atom has different significance in chemistry, mainly in structure or shape determination of any molecule. In this step, connect both chlorine atoms to the iodine central atom with the help of a single bond. C With three bonding pairs and one lone pair, the structure is designated as AX3E and has a total of four electron pairs (three X and one E). This special configuration gives the atom an extra stability. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Welcome to Techiescientist.com. 3.

Bond length in ICl2- and ICl2+ - Chemistry Stack Exchange To count the valence electron in ICl2- molecule, look at the periodic group of iodine and chlorine atom in the periodic table. The process of drawing the lewis structure is described below-, Total nonbonding electrons in ICl2 is { 6 + (62) } = 18, The factor hybridization plays the most significant role in structure determining. X represent the bonded atoms to the central atom, as we know, iodine is bonded with two chlorine atoms. Which one of the following molecules is nonpolar? With 18 valence electrons, the Lewis electron structure is shown below. Accessibility StatementFor more information contact us atinfo@libretexts.org. . The FaxialSFaxial angle is 173 rather than 180 because of the lone pair of electrons in the equatorial plane. However, I remember our first inorganic chemistry lecture talk about how to predict interhalogen compounds and their ions with the explicit step of giving the central atom (iodine) the charge, drawing 2-electron 2-centre bonds until octet and filling in the remaining atoms. Axial groups are thus more crowded than the equatorial positions with only two adjacent groups at 90. A passion for sharing knowledge and a love for chemistry and science drives the team behind the website. This compound has a square planar molecular geometry with equal90o bond angle. Hybridization also helps to determine the bond angle in a molecule. Perhaps you or @Martin- could perform a better calculation? Bond angle is nothing but the angle between two covalent bonds. But due to the repulsion the actual geometrical structure is deviated and the shape of the molecule becomes T-shaped. As we see in the above figure, the iodine central atom gets 10 electrons(6 represented as dot + 2 single bonds) in its outer shell and violates the octet rule. Experts are tested by Chegg as specialists in their subject area. means that the iodine atom is contracted and the two chlorines can move closer. ICl5 Lewis Structure, Geometry, Hybridization, and Polarity Due to its linear shape, it is a nonpolar molecule. The nature of ICl2- is nonpolar because all dipoles that generated along the bond will cancel out because of its symmetrical geometry of it. Molecular shape is changed with the change of central atom hybridization (shown below).Hybridization of central atomStructurespLinearsp2Trigonal planarsp3Tetrahedralsp3dTrigonal bipyramidalsp3d2Octahedral, Not only hybridization, some times lone pair bond pair repulsion also determines the structure of any molecule. The central atom, sulfur, has 6 valence electrons, as does each oxygen atom. 1) how do their frequencies compare? ICl5is a neutrally charged compound that has an octahedral geometry and a . What level of computation did they use? ICl2 is an interhalogen compound in which iodine is connected with two chlorine atoms by two covalent bonds. The $\ce{ICl2+}$ ion can thus be explained by assuming one double-filled s- and one double filled p-orbital plus two half-filled p-orbitals on iodine. Question: What is the value of the bond angle in ICl2? More electronegative atom is attracted the electrons more towards itself than less electronegative atom. @Jan Thanks for pointing out the theoretical geometry for the cation. But this is not the issue, some elements can violate the octet to gains stability. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. F. Bailly, P. Barthen, H.-J. Now count the remaining valence electrons. The bond angle in ICl 2 . Although there are lone pairs of electrons, with four bonding electron pairs in the equatorial plane and the lone pairs of electrons in the axial positions, all LPBP repulsions are the same. Now start placing the remaining valence electrons on the outer atom(chlorine) to complete their octet i.e. Each iodine atom contributes seven electrons and the negative charge one, so the Lewis electron structure is. With no lone pair repulsions, we do not expect any bond angles to deviate from the ideal. Hence, the molecular geometry of an iodine trichloride compound will be different from its actual shape. Now count the valence electrons we used in the above structure. What are the expected bond angles in ICl4? ICl 5: 6: 1 : octahedral: square pyramid: 90, 180: sp 3 d 2: XeF 4 * 6: 2 : octahedral: square planar: Ubuntu won't accept my choice of password.

By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. These electron pairs (lone pair + bond pair) will repel each other and tried to go far away to minimize the repulsion. This molecular structure is square pyramidal. Geometry of Molecules - Chemistry LibreTexts First, count the formal charge on the chlorine atom. Also, the iodine central atom in ICl2- lewis structure violates the octet as it is holding more than 8 electrons in its octet shell. ICl2- is an interhalogen compound in which iodine is connected with two chlorine atoms by two covalent bonds. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. According to VSEPR theory, lone pair should be placed in equatorial position due to greater stability. In most of the cases valance electrons participate in chemical reaction due to availability of them rather than the inner shell electrons because the attraction of nucleus on valance shell is the least with comparing to inner shell electrons. Molecular Geometry - University of Illinois Urbana-Champaign Compared to a bond order of for $\ce{ICl2-}$ this means a shorter bond length. 1. The Lewis electron structure is, 2. Hence, the cancellation of dipole and symmetric geometry makes the ICl2- nonpolar in nature. In nonpolar molecules, charges are the same, hence, all dipole is canceled out. See Answer Question: What are the expected bond angles in ICl4+? ICl3 has three bond pairs and two lone pairs of electrons. The bond angle of ICl3 is approximately 107 degrees. The arrangement of five groups around a central atom results in a trigonal bipyramidal electronic geometry. But this chart can only be followed if any repulsion is absent in the molecule. We aim to make complex subjects, like chemistry, approachable and enjoyable for everyone. The Difference in the Space Occupied by a Lone Pair of Electrons and by a Bonding Pair. Thy are-. Hope you enjoy reading this article and related doubts are most welcome. The T shape and trigonal bipyramidal geometry of iodine trichloride lead to a bond angle (Cl-I-Cl) slightly smaller than 90 and greater than 180 due to prominent lone pair-lone pair repulsions than bond pair-bond pair repulsions. In ammonia, the central atom, nitrogen, has five valence electrons and each hydrogen donates one valence electron, producing the Lewis electron structure. Conclusion. In this article, icl3 lewis structure different facts on ICl3 like lewis structure, hybridization, shape, formal charge calculation, stability and uses with detailed explanations are discussed briefly. I'm not convinced that a 15 year old calculation has predicted the correct geometry. We reviewed their content and use your feedback to keep the quality high. He holds a degree in B.Tech (Chemical Engineering) and has four years of experience as a chemistry tutor. In the previous section, we saw how to use VSEPR to predict the geometry around a central atom based on the number of groups attached to a central atom. There are three different molecular geometries that are possible in this category: One of the limitations of Lewis structures is that they depict molecules and ions in only two dimensions. Icl Bond Angle - Mad Wire Build ICL2 | Bond Angle, Molecular Geometry & Hybridization | Polar Or Non Polar The molecular geometry and shape of the molecule can be predicted from the following table: As per the table, ICl3 resembles AX3E3 due to the presence of three bond pairs and two lone pairs of electrons on the central atom, Iodine. ICl2 is an extremely reactive and unstable chemical not often encountered in the natural world. 3.2.1: Lone Pair Repulsion - Chemistry LibreTexts The bond angle in ICl2- molecule is 180. But iodine is negatively charged in ICl2 and I has eight electrons in its valance shell. These arguments tell us that we would have shorter bond lengths in $\ce{ICl2^{+}}$ compared to $\ce{ICl2^{-}}$. Expert Answer. The trigonal bipyramidal geometry and electronegativity difference between chlorine and an iodine atom gave insight regarding the polar nature of ICl3. In the above structure, we use two single bonds for connecting both side chlorine atoms to the iodine central atom. Experimentally we would expect the bond angle to be approximately 180.ICl2- Lewis Structure: https://youtu.be/ETwlsi97h-ETo determine the molecular geometry, or shape for a compound like ICl2 - , we complete the following steps:1) Draw the Lewis Structure for the compound.2) Predict how the atoms and lone pairs will spread out when the repel each other.3) Use a chart based on steric number (like the one in the video) or use the AXN notation to find the molecular shape. But due to presence of these lone pair, the actual structure is distorted and it becomes linear. Chlorine trifluoride has 5 areas of electron density around the central chlorine atom . The ion has an III angle of 180, as expected. The actual bond angles are similar, but not exactly the same, as those predicted based on the total number of groups (the "parent" geometry). From the hybridization the predicted structure is trigonal bipyramidal. They both have seven electrons in their respective valance shell. Therefore. The bond angles are all about 107 o. 2. 4. Experimental data for ICl (Iodine monochloride) - NIST This special electron configuration gives any atom an extra stability. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. There are two different molecular geometries that are possible in this category: 1. It only takes a minute to sign up. The molecular geometry of molecules with lone pairs of electrons isbetter predicted when we consider that electronic repulsion created by lone pairs is stronger than the repulsion from bonded groups. In ICl2, central atom, iodine is sp3d hybridized having three lone pair and two bond pair. Calculation of formal charge also helps to find out the most stable lewis structure of any molecule. Repulsions are minimized by directing the bonding pairs and the lone pairs to the corners of a tetrahedron. The three equatorial positions are separated by 120 from each other, and the 2 axial positions are at 90 to the equatorial plane. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. In the solid state it forms the dimer (I2Cl6) with two bridging chlorine atoms. The total valence electron is available iodine dichloride lewis structure is 22. If we place it in the equatorial position, we have two 90 LPBP repulsions at 90. Some of the great evidences of the covalency of ICl3 are-. Many elements result in variations from the ideal bond angles of a molecular form. But each of the chlorine atom obeys octet rule in ICl2 molecule. Smaller electronegativity difference between iodine and chlorine. The valence-shell electron-pair repulsion (VSEPR) model allows us to predict which of the possible structures is actually observed in most cases. Episode about a group who book passage on a space ship controlled by an AI, who turns out to be a human who can't leave his ship? 4. ICl3 is bright yellow solid, which turns into red color upon exposure to light due to the formation of elemental iodine. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. 6. The orbital diagram of Iodine trichloride is given below: The Lewis structure is shown in detail in the following video. Valance electrons are those who are revolving around the nucleus from the outer most shell of any atom. B There are three electron groups around the central atom, two bonding groups and one lone pair of electrons. Lone pairs or nonbonding electrons are two similar words. Techiescientist is a Science Blog for students, parents, and teachers. The dipole moment of two opposite Cl-I bonds will not cancel out because the Cl-I-Cl bond angle is not exactly 180 but greater than 180 owing to lone pair- lone pair repulsions. The O-S-O bond angle is expected to be less than 120 because of the extra space taken up by the lone pair. The drawing of the Lewis structure of any compound consists of the following steps: The electronic configuration of I and Cl is [Kr] 4d105s25p5 and [Ne] 3s23p5, respectively. This results in a linear molecular geometry with 180 bond angles. $\ce{I}$ in $\ce{ICl+}$ is $sp^3$ hybridized. Iodine is connected with three chlorine atoms through three sigma bonds. In this interhalogen compound, ICl3, both the participating atoms (iodine and chlorine) have same number of valance electrons. If both lone pairs of electrons occupy the axial position, then there will be overall six lone pair-bond pair repulsions at 90 whereas if they occupy the equatorial position, then there will be four lone pair-bond pair repulsions at 90 . The bond angles in ICl2 range from 180 degrees, the highest possible angle that can be achieved in a linear, angular geometry. A) NH 3 B) OF 2 C) CH 3 . So, put these 6 remaining valence electrons around the iodine central atom. The molecular geometry for ICl 4-_____is and the approximate value of the Cl-I-Cl bond angle is _____ ? Illustration of the Area Shared by Two Electron Pairs versus the Angle between Them. The molecule of iodine trichloride (with trigonal bipyramidal shape ICl3 molecular geometry) is tilted at slightly smaller than 90 degrees bond angle of Cl-I-Cl. A less electronegative atom is capable to share more electrons, hence, the least electronegative atom takes the middle position in the lewis diagram. See Answer. The total number of valence electron are [(7 X 1) + (7 X 3)] = 28 electrons. Otherwise, the shape is deviated from its actual geometrical structure. ICl2 is moderately stable compound. We aim to make complex subjects, like chemistry, approachable and enjoyable for everyone. The two lone pair of iodin is placed in the equatorial position and rest of the position of TBP structure is substituted by three chlorine atoms (one equatorial and two axial position). Enter the bond angle of the molecule. In ICl3, the above three types of repulsion of present due to having the lone pair of central atom (Iodin). Each of the chlorine atom shares their only one valance electron with iodine in this hybridization. All the carbons are surround by four objects. Notify me of follow-up comments by email. The 3-center 3-electron bond model (for the cation) would have the chlorines further apart and still have the lone pairs in low energy sp or (s and p) orbitals. So, Is ICl2- polar or nonpolar? Thus, the ring would be expected to pucker since flatness can occur only if C has three objects around it. Why is an ionic bond a chemical and not a physical bond? 06 May 2022 Icl Bond Angle Trend As per the rules of the idea it can be simply evaluated that the construction of ICl4+ is the sq. It leads to the excited-state electronic configuration of iodine as [Kr] 4d105s25p45d1. But the iodine atom already has 4 electrons in its octet because of two single bonds connected to it. Frohn, M. Kckerling, Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI. One of the characteristics of this structure is that nonbonding electrons are shown around the respective atoms. Inner shell electrons are very strongly attracted by the nucleus. As per the rules of the idea it can be simply evaluated that the construction of ICl4+ is the sq. Both of these words are carrying same meaning in chemistry. I in $\ce{ICl2-}$ is $sp^3d$ hybridized. There are three nuclei and one lone pair, so the molecular geometry is trigonal pyramidal. However, our previous discussion was limited to the simple cases where all of the groups were bonded groups (i.e., in the designation AXmEn , n=0). Sp3d hybridization directs a molecule to be TBP structured but due to presence of three lone pair, its actual geometrical structure is violated and becomes linear. Basically, nonbonding electrons or lone pairs are those valance electrons left after bond formation. So, we get the Sp3d hybridization for ICl2- molecule for a steric number of five. The main difference between a covalent compound and ionic compound is that in covalent compound valance electrons are shared between the atoms and in ionic compound valance electrons are donated from one atom to another atom. Iodine is connected by two covalent bonds with two chlorine atoms. 1. a six-membered ring of carbon atoms, is not flat but instead has a puckered, Predict the values of the C-C-C bond angles. (7 6 4/2) = -1 formal charge on the iodine central atom. This is essentially a trigonal bipyramid that is missing two equatorial vertices. The geometry of ICl3 is trigonal bipyramidal with a T-shaped molecular shape. Since additional promotion energy is required to form the $sp^3d$ hybrid compared to the $sp^3$ hybrid, the bond lengths in $\ce{ICl2-}$ is longer. Thus, the total nonbonding electrons in ICl3 = {4 + (36)} = 22 or 11 pair of lone electrons. Due to presence of two lone pair of iodine, two chlorine atoms are placed in the two axial position of TBP structure. However, because the axial and equatorial positions are not chemically equal, where will we place the lone pair? In $\ce{ICl2+}$, we have to bonds with a bond order of 1 to each of the chlorines. Because lone pairs occupy more space around the central atom than bonding pairs, electrostatic repulsions are more important for lone pairs than for bonding pairs. Therefore, these elements can be surrounded by more than eight electrons. Hence, (one single bond + 6 valence electron as dots) means a total of 8 valence electrons are present around each chlorine atom, hence, both of them completed their octet comfortably. 1. Three lone pairs and two bond pairs are involved in this molecular species. PDF AP CHEMISTRY 2006 SCORING GUIDELINES (Form B) - College Board With three nuclei and three lone pairs of electrons, the molecular geometry of I3 is linear. In $\ce{ICl2^{-}}$ we have added another electron and it will go into the nonbonding orbital. 3. Therefore, the electron pairs will occupy the space to minimize the repulsion and maximize the distance between them. Placing them in the equatorial positions eliminates 90 LPLP repulsions and minimizes the number of 90 LPBP repulsions. For $\ce{ICl2-}$, if we let $\ce{I}$ be $sp^2$ hybridized such that the 3 lone pairs lie 120 apart in a plane, and then let the 2 $\ce{Cl}$ atoms and the $\ce{I}$ atom lie in a straight line, then we can form a 3-centred, 4 electron system. The geometry of the ion would, due to this fact, be square waves a and b shown above are propagating in the same medium. ICl4- Molecular Geometry, Bond Angles & Electron Geometry Wayne Breslyn 634K subscribers Subscribe 24K views 2 years ago An explanation of the molecular geometry for the ICl4- ion. As with SO2, this composite model of electron distribution and negative electrostatic potential in ammonia shows that a lone pair of electrons occupies a larger region of space around the nitrogen atom than does a bonding pair of electrons that is shared with a hydrogen atom. This results in an electronic geometry that is approximately trigonal planar. Iodine trichloride (ICl3) is an interhalogen compound and it has different uses in industry like-, Shape of any molecular species can be determined by hybridization, SN2 Examples: Detailed Insights And Facts, Stereoselective vs Stereospecific: Detailed Insights and Facts, Formal charge of iodine = 7 4 (6/2) = 0, Formal charge of each of the chlorine atom = 7 6 (2/2) = 0, Nonbonding electrons on Iodine (I) = 7 3 = 4 or 2 lone pair.
