QUESTION 7. Compound A has the formula C8H8. It reacts rapidly with KMnO4to give CO₂ and a carboxylic acid, B (C7H6O₂), but reacts with only 1 equiv of H₂on catalytic hydrogenation over a palladium catalyst. On hydrogenation under conditions that reduce aromatic rings, 4 equiv of H₂ are taken up, and hydrocarbon C (C8H16) is produced. What are the structures of A, B, and C?Formulate the reactions.
