    Acetone reacts with iodine to form iodoform in the presence of                                                               [BHU 2004; CPMT 2004]

    A)                 \[CaC{{O}_{3}}\]              

    B)                 \[NaOH\]

    C)                 \[KOH\]               

    D)                 \[MgC{{O}_{3}}\]

    Correct Answer: B

    Solution :

               Acetone on iodination gives iodoform in the presence of NaOH                    \[\underset{\text{Acetone}}{\mathop{\overset{\overset{O}{\mathop{||}}\,}{\mathop{C{{H}_{3}}-C-C{{H}_{3}}}}\,}}\,+3{{I}_{2}}+4NaOH\xrightarrow{-3{{H}_{2}}O}\]\[\underset{\text{Iodoform}}{\mathop{CH{{I}_{3}}}}\,+\underset{\text{Sodium acetate}}{\mathop{C{{H}_{3}}COONa}}\,+\underset{\text{Sodium iodide}}{\mathop{3NaI}}\,\]
