    B)                         \[C{{H}_{3}}OH\]

    C)                         \[CH3CHO\]     

    D)                         \[C{{H}_{3}}COC{{H}_{3}}\]

    Correct Answer: D

    Solution :

    \[C{{H}_{3}}-\underset{O}{\mathop{\underset{||}{\mathop{C}}\,}}\,-\] or    \[C{{H}_{3}}-\underset{OH}{\mathop{\underset{|}{\mathop{CH}}\,}}\,-\] group have carbonyl compounds and alcohol haloform test. \[C{{H}_{3}}-\underset{O}{\mathop{\underset{||}{\mathop{C}}\,}}\,-\xrightarrow{{{I}_{2}}+NaOH}CH{{I}_{3}}\]
