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

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

Step-by-step explanation:

Hyposulphite (so₂²⁻) is polyatomic ion .

According to VSEPR model

Total elrctron pairs
`=(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
`=(1)/(2)[6+0-0+2]= 4`

That is two bond pairs and two lone pairs
