    A)                 \[2C{{H}_{3}}COON{{H}_{4}}\]

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

    C)                 \[C{{H}_{3}}CON{{H}_{2}}+C{{H}_{3}}COON{{H}_{4}}\]

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

    Correct Answer: C

    Solution :

                    \[\begin{matrix}    C{{H}_{3}}CO  \\    C{{H}_{3}}CO  \\ \end{matrix}\,>O+2N{{H}_{3}}\to \underset{\text{Acetamide}}{\mathop{C{{H}_{3}}CON{{H}_{2}}}}\,+\underset{\text{Ammonium acetate}}{\mathop{C{{H}_{3}}COON{{H}_{4}}}}\,\]
