    Which of the following does not participate in the carbylamine reaction?

    A)  Aniline                                

    B)  Chloroform

    C)  Ethanol                               

    D)  KOH

    Correct Answer: C

    Solution :

                     Carbyl amine reaction Only primary amines\[(-N{{H}_{2}})\] gives this reaction. In this reaction primary amine reacts with chloroform and caustic potash solution to give a bad smelling compound isocyanides e.g., \[R-N{{H}_{2}}+CHC{{l}_{3}}+3KOH\xrightarrow{{}}\]\[R-NC+3KCl+3{{H}_{2}}O\] So, ethanol does not participate in the reaction.
