The ions ClO3− and SO32− each have 42 electrons and a central atom with sp3 hybridization. Since the central atom in both has one lone pair, their molecular shape is best described as:

1. Straight-line
2. Triangular planar
3. Triangular pyramid
4. Angular

Correct answer: Triangular pyramid

Solution

Both ClO3− and SO32− have sp3 hybridization with one lone pair on the central atom, resulting in a pyramidal geometry due to lone pair-bond pair repulsion.
