Question

Number of lone pairs of electrons in the central atom of , ,  and , respectively, are

Canvas Classes · Accepted Answer

Step 1 — Count lone pairs on central atom:

: S has 2 bonds + 2 lone pairs (like )

: Central O has 2 bonds + 1 lone pair

: Cl has 3 bonds + 2 lone pairs (T-shaped)

: S has 6 bonds + 0 lone pairs (octahedral)

Step 2 — Summary: 2, 1, 2, 0

Answer: Option (2) — 2, 1, 2 & 0
