    An organic compound containing nitrogen atom is when treated with the mixture of reagent used in Riemer Tiemann reaction reagent in \[1 : 3\] ratio, it produces methyl isocyanide. The organic compound is

    A)  \[{{\operatorname{CH}}_{3}}N{{H}_{2}}\]                 

    B)  \[{{\operatorname{CH}}_{3}}C{{H}_{2}}N{{H}_{2}}\]

    C)  \[{{\operatorname{CH}}_{3}}CO\,N{{H}_{2}}\]          

    D)  \[{{\operatorname{CH}}_{3}}C{{H}_{2}}CO\,N{{H}_{2}}\]

    Correct Answer: A

    Solution :

    This reaction is carbylamine reaction. \[{{\operatorname{CH}}_{3}}N{{H}_{2}}\,\,\xrightarrow{CHC{{l}_{3}}+3KOH}\,\,R-N\overset{\to }{\mathop{\,=}}\,\,\,C\] Riemer-Tiemann reaction reagent \[= \,CHC{{l}_{3}} + KOH\]
