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

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
