    Which of the following compound reacts with chloroform and a base to form phenyl isocyanide?              [MHCET 2003]

    A)                 Phenol 

    B)                 Aniline

    C)                 Benzene             

    D)                 Nitro benzene

    Correct Answer: B

    Solution :

               We know that            \[\underset{\text{Aniline}}{\mathop{{{C}_{6}}{{H}_{5}}N{{H}_{2}}}}\,+\underset{\text{Chloroform}}{\mathop{CHC{{l}_{3}}}}\,+3KOH\to \underset{\text{phenyl isocyanide}\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,}{\mathop{{{C}_{6}}{{H}_{5}}NC+3KCl+3{{H}_{2}}O}}\,\] Thus in this reaction phenyl isocyanide is produced. this is called carbylamine reaction.
