    10. In an abandoned laboratory has been found a flammable liquid, A, in a bottle bearing only the label "Compound A: ." Compound A reacts with 1 mol equiv of hydrogen and, after treatment with acidic , gives the dicarboxylic acid C (see below). Another bottle from the same laboratory is labeled "Compound B (isomer of A)." Compound B also reacts with 1 mol equiv of hydrogen, but yields cyclohexanone after treatment with acidic .

    How many degrees of Unsaturation does compound A possess?

    Suggest structures for A and B.

    What was the other product formed in the KmnO4 oxidation of B?
