An unknown hydrocarbon A, with formula C6H12, reacts with 1 molar equivalent ofH2 over palladiumcatalyst. Hydrocarbon A also reacts with OsO4 to give a diol, B. When oxidized withKMnO4 in acidicsolution, A gives two fragments. One fragment is propanoic acid,CH3CH2COOH, and theother fragment is a ketone, C. What are the structures of A, B, andC?
