Chemistry - Hydrocarbon Question with Solution | TestHub

Given compound has C=C + C=O (α,β-unsaturated ketone).

Product shows C=O reduced to –CH₂, while C=C remains unchanged.

So we need selective carbonyl reduction only.

LiAlH₄ reduces C=O → alcohol, then further to alkane (after workup).

Other reagents either reduce C=C or give different products.
