An unknown compound X, C7H12, reacts with excess H2 in presence of Pt Catalyst to give C7H16. Heating of X with KmnO4/OH-, followed by acidification, gives compound Z with molecular formula C4H6O4, CH3CO2H and CO2. Both X and Y are optically active, while Z is optically inactive. Propose structures for X, Y and Z that are consistent with these data.
