    On vigorous oxidation by permangnate solution \[{{(C{{H}_{3}})}_{2}}C=CHC{{H}_{2}}CHO\] gives   AIEEE  Solved  Paper-2002

    A) \[{{(C{{H}_{3}})}_{2}}CO\] and \[OHCC{{H}_{2}}CHO\]

    B) \[{{(C{{H}_{3}})}_{2}}\underset{\begin{smallmatrix}  | \\  OH \end{smallmatrix}}{\mathop{C}}\,-\underset{\begin{smallmatrix}  | \\  OH \end{smallmatrix}}{\mathop{C}}\,HC{{H}_{2}}CHO\]

    C) \[{{(C{{H}_{3}})}_{2}}CO\] and \[OHCC{{H}_{2}}COOH\]

    D) \[{{(C{{H}_{3}})}_{2}}CO\] and \[C{{H}_{2}}{{(COOH)}_{2}}\]

    Correct Answer: D

    Solution :

    \[C=C\] bond is cleaved and oxidised to \[-COOH\], \[-CHO\] group is also oxidised to \[-COOH\]. \[{{(C{{H}_{3}})}_{2}}C=CHC{{H}_{2}}CHO\] \[(C{{H}_{3}})C=O+HOOC-C{{H}_{2}}-COOH\]
