    The product D of the reaction                 \[C{{H}_{3}}Cl\xrightarrow{KCN}(A)\xrightarrow{{{H}_{2}}O}(B)\xrightarrow{N{{H}_{3}}}(C)\xrightarrow{\Delta }(D)\] is [MP PET 1997]

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

    B)                 \[C{{H}_{3}}CN\]

    C)                 \[HCON{{H}_{2}}\]         

    D)                 \[C{{H}_{3}}CON{{H}_{2}}\]

    Correct Answer: D

    Solution :

               \[C{{H}_{3}}Cl\underset{-KCl}{\mathop{\xrightarrow{KCN}}}\,C{{H}_{3}}CN\xrightarrow{{{H}_{2}}O}C{{H}_{3}}COOH\]                                                 \[\xrightarrow{N{{H}_{3}}}C{{H}_{3}}COON{{H}_{4}}\xrightarrow{\Delta }C{{H}_{3}}CON{{H}_{2}}\]
