Question: Compound A has the formula C 8 H 8 . It reacts rapidly with acidic KMnO 4 but reacts with only 1 equivalent of H

Compound A has the formula C₈H₈. It reacts rapidly with acidic KMnO₄ but reacts with only 1 equivalent of H₂ over a palladium catalyst. On hydrogenation under conditions that reduce aromatic rings, A reacts with 4 equivalents of H₂, and hydrocarbon B, C₈H₁₆, is produced. The reaction of A with KMnO₄ gives CO₂ and a carboxylic acid C, C₇H₆O₂.

What are the structures of A, B, and C? Write all the reactions.
