Hyposulfite, SO22–, is a polyatomic ion that has not yet been definitively confirmed to exist. However, the VSEPR model may still be applied to yield a prediction on its molecular geometry. What is the most reasonable estimate for the O–S–O bond angle in hyposulfite?

The most reasonable estimate for the O–S–O bond angle in hyposulfite = 106°

Explanation:

Hyposulphite (so₂²⁻) is polyatomic ion .

According to VSEPR model

Total elrctron pairs  

V = Valence shell electrons of central element

X = No. of monovalent surrounding atoms

C = Cationic charge

A = Anionic charge

Total electron pairs

That is two bond pairs and two lone pairs
