The <strong>valence electron count<\/strong> shows that iodine follows the <strong>expanded octet rule<\/strong>, meaning it accommodates more than 8 electrons due to its position in Period 5 of the periodic table.<\/p>\n\n\n\n<p>When drawing the Lewis structure, we begin by identifying the total <strong>valence electrons<\/strong> (28). We assign iodine as the <strong>central atom<\/strong> since it is the <strong>least electronegative<\/strong>. Three single bonds are formed between iodine and chlorine, consuming 6 electrons. Each chlorine gets 6 more electrons to complete their octets, using <strong>18 more electrons<\/strong>, leaving <strong>4 electrons<\/strong> for iodine. These 4 electrons remain as <strong>two lone pairs<\/strong> on iodine.<\/p>\n\n\n\n<p>The molecular geometry is determined using <strong>VSEPR (Valence Shell Electron Pair Repulsion) theory<\/strong>. The <strong>AX\u2083E\u2082 notation<\/strong> (3 bonded atoms + 2 lone pairs) suggests a <strong>T-shaped<\/strong> structure. The <strong>lone pairs<\/strong> on iodine cause a <strong>bent geometry<\/strong> instead of a perfect trigonal planar shape.<\/p>\n\n\n\n<p>Additionally, ICl\u2083 exhibits <strong>dipole moments<\/strong> due to an <strong>asymmetrical charge distribution<\/strong>, making it <strong>polar<\/strong>. The presence of <strong>lone pairs<\/strong> affects its shape and polarity, causing repulsion among bonded and non-bonded electron pairs. This leads to deviations from an ideal trigonal planar shape.<\/p>\n\n\n\n<p>In summary, the <strong>Lewis structure of ICl\u2083<\/strong> follows the <strong>expanded octet rule<\/strong>, displays a <strong>T-shaped geometry<\/strong>, and is <strong>polar<\/strong> due to lone pair-bond pair repulsions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Draw the Lewis structure for ICl3 The correct answer and explanation is : Lewis Structure of ICl\u2083 The Lewis structure of ICl\u2083 (Iodine trichloride) consists of an iodine (I) atom at the center bonded to three chlorine (Cl) atoms and one lone pair of electrons on iodine.
