    Mendius reaction converts an alkyi cyanide to

    A)  a primary amine

    B)  an aldehyde

    C)  a ketone        

    D)  an oxime

    Correct Answer: A

    Solution :

     The reduction of alkyl and aryl cyanides to primary amines with nascent hydrogen is known as Mendius reaction. \[C{{H}_{3}}CN+4[H]\xrightarrow{Na/{{C}_{2}}{{H}_{5}}OH}C{{H}_{3}}C{{H}_{2}}N{{H}_{2}}\] \[RCN+4[H]\xrightarrow{Na/{{C}_{2}}{{H}_{5}}OH}\underset{{{1}^{o}}\text{amine}}{\mathop{RC{{H}_{2}}N{{H}_{2}}}}\,\]
