    lodoform test is not answered by:

    A)  \[C{{H}_{3}}OH\]    

    B)  \[{{C}_{2}}{{H}_{5}}OH\]

    C)  \[C{{H}_{3}}COC{{H}_{3}}\]

    D) \[C{{H}_{3}}\underset{\begin{smallmatrix}  | \\  OH \end{smallmatrix}}{\mathop{CH}}\,C{{H}_{3}}\]

    Correct Answer: A

    Solution :

     Only those compound give lodoform test which has \[C{{H}_{3}}\overset{\begin{smallmatrix}  OH \\  | \end{smallmatrix}}{\mathop{CH}}\,-\]or\[C{{H}_{3}}\overset{\begin{smallmatrix}  O \\  || \end{smallmatrix}}{\mathop{C}}\,-\]group. Hence, Methonal does not give lodoform test.
