    What will be the final product in the following reaction sequence - \[C{{H}_{3}}C{{H}_{2}}CN\xrightarrow{{{H}^{+}}/{{H}_{2}}O}A\xrightarrow{N{{H}_{3}}}B\xrightarrow{NaOBr}C\]

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

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

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

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

    Correct Answer: C

    Solution :

    \[C{{H}_{3}}C{{H}_{2}}CN\xrightarrow{{{H}^{+}}/{{H}_{2}}O}C{{H}_{3}}C{{H}_{2}}COOH\xrightarrow[\Delta ]{N{{H}_{3}}}\]\[C{{H}_{3}}C{{H}_{2}}CON{{H}_{2}}\xrightarrow[NaOBr]{Hoffman\,\,bromied\,\,reaction}C{{H}_{3}}C{{H}_{2}}N{{H}_{2}}\]
