  • question_answer Which of the following reactions does not yield an amine [CPMT 1989, 93]

    A)                 \[RX+N{{H}_{3}}\xrightarrow{{}}\]

    B)                 \[RCH=NOH+[H]\underset{{{C}_{2}}{{H}_{5}}OH}{\mathop{\xrightarrow{Na}}}\,\]

    C)                 \[RCN+{{H}_{2}}O\xrightarrow{{{H}^{+}}}\]

    D)                 \[RCON{{H}_{2}}+4H\xrightarrow{LiAl{{H}_{4}}}\]

    Correct Answer: C

    Solution :

               \[R-CN+{{H}_{2}}O\xrightarrow{{{H}_{2}}O/{{H}^{+}}}RCOOH+N{{H}_{3}}\]         It yield amine when reduced as ?                                 \[R-CN+{{H}_{2}}\to R-C{{H}_{2}}-N{{H}_{2}}\]
