Question

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?

Answer 1

Answer:

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  $=\frac{1}{2} [V+X -C+A]$

V = Valence shell electrons of central element

X = No. of monovalent surrounding atoms

C = Cationic charge

A = Anionic charge

Total electron pairs $=\frac{1}{2}[6+0-0+2]= 4$

That is two bond pairs and two lone pairs
