    On vigorous oxidation by permanganate solution \[{{(C{{H}_{3}})}_{2}}C=CH-C{{H}_{2}}-C{{H}_{3}}\]gives.

    A)  \[C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  C{{H}_{3}} \end{smallmatrix}}{\overset{\begin{smallmatrix}  OH \\  | \end{smallmatrix}}{\mathop{C}}}\,-\underset{{}}{\overset{\begin{smallmatrix}  OH \\  | \end{smallmatrix}}{\mathop{C}}}\,H-C{{H}_{2}}C{{H}_{3}}\]

    B)  

    C)  

    D)  

    Correct Answer: D

    Solution :

    \[{{(C{{H}_{3}})}_{2}}C=CH-C{{H}_{2}}-C{{H}_{3}}\xrightarrow[{}]{KMn{{O}_{4}}}\]\[{{(C{{H}_{3}})}_{2}}C=O+HOOCC{{H}_{2}}C{{H}_{3}}\]
