Question: Compound A has the formula C8H8. It reacts rapidly with KMnO4 to give CO2 and a carboxylic acid, B (C7H6O2), but reacts with only 1

Compound A has the formula C8H8. It reacts rapidly with KMnO4 to give CO2 and a carboxylic acid, B (C7H6O2), but reacts with only 1 molar equivalent of H2 on catalytic hydrogenation over a palladium catalyst. On hydrogenation under conditions that reduce aromatic rings, 4 equivalents of H2 are taken up and hydrocarbon C (C8H16) is produced. What are the structures of A, B, and C? Write the reactions.
