The hybridisation of central iodine atom in IF5, I3^- and I3^+ are respectively : — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Calculate the steric number for each iodine species: - IF5: 5 bond pairs + 1 lone pair = 6 domains -> sp3d2. - I3-: 2 bond pairs + 3 lone pairs = 5 domains -> sp3d. - I3+: 2 bond pairs + 2 lone pairs = 4 domains -> sp3. Step 2: Check the calculated hybridizations against the options. Step 3: The hybridizations are sp3d2, sp3d, and sp3 respectively, matching option (a).
