Question

6. An organic compound U with molecular formula C19H38 gave 2, 6, 12, 14- tetramethylpentadecane on hydrogenation. Ozonolysis of U gave propanone and a 16- carbon aldehyde V as products. Give the structures of U and V and provide the name for U. 7. An unknown hydrocarbon Q has a formula CaH12. Q Reacts with osmium tetroxide to give a diol R. When oxidized with KM O4 in an acidic medium, Q gives two products. One product is propanoic acid and the other a ketone S. Provide reaction equations to identify the possible structures of Q, R and S.
