Step 1: Analyse each molecule/ion

A.  (iodine dichloride anion)

I has 7 valence e⁻ + 1 (negative charge) = 8 e⁻; forms 2 bonds with Cl

Bond pairs = 2, Lone pairs on I =  → BP:LP = 2:3 → III

B.

O has 6 valence e⁻; forms 2 bonds with H

Bond pairs = 2, Lone pairs on O = 2 → BP:LP = 2:2 → IV (written as "2 L 2")

C.

S has 6 valence e⁻; in : one S=O double bond, one S→O dative bond, 1 lone pair on S

Effective: Bond pairs = 4 (counting double bond as 2 pairs? No — in VSEPR: 3 electron domain
