    A)  it undergoes esterification with carboxylic acid

    B)  it reacts with ammonia

    C)  it forms yellow crystals of iodoform

    D)  it liberates\[{{H}_{2}}\]with Na metal

    Correct Answer: C

    Solution :

                    lodoform test is given by those compounds which has\[C{{H}_{3}}-\underset{\begin{smallmatrix}  || \\  O \end{smallmatrix}}{\mathop{CH}}\,-C/H\]or \[C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  OH \end{smallmatrix}}{\mathop{CH}}\,-\]units. Hence, this test is not given by phenol \[({{C}_{6}}{{H}_{5}}-OH)\].
