  • question_answer
    \[\begin{align}   & C{{H}_{3}}C{{H}_{2}}Cl\xrightarrow{NaCN}X\xrightarrow[{}]{Ni/{{H}_{2}}}Y- \\  & | \\  & Z\xleftarrow{\text{Acetic anhydride}}| \\ \end{align}\]  [AIPMT 2002]

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

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

    C) \[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}CONHC{{H}_{3}}\]

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

    Correct Answer: A

    Solution :

    [a] \[C{{H}_{3}}C{{H}_{2}}Cl\xrightarrow[{}]{NaCN}C{{H}_{3}}-\underset{'X'}{\mathop{C{{H}_{2}}}}\,-CN\]            \[\xrightarrow[{}]{Ni/{{H}_{2}}}C{{H}_{3}}-\underset{Y}{\mathop{C{{H}_{2}}C{{H}_{2}}N{{H}_{2}}}}\,\underset{anhydride}{\mathop{\xrightarrow{Acetic}}}\,\]             \[C{{H}_{3}}-C{{H}_{2}}-\underset{'Z'}{\mathop{C{{H}_{2}}}}\,-NHCOC{{H}_{3}}\]
