Question

Shape of sulphite ion is:

• A. square planar
• B. pyramidal
• C. angular
• D. linear

Answer 1

The correct option is B pyramidal

Sulphite ion is $S{O}_3^{-2}$

Valence electron:$6+3\times 6+2=26$

Hybridization:$s{p}^3$

Geometry:tetrahedral

Shape: pyramidal (one position occupied by lone pair of electrons)

Hence, option $B$ is correct.
