    The refluxing of\[{{(C{{H}_{2}})}_{2}}NCOC{{H}_{3}}\]with acid gives:

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

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

    C)  \[{{(C{{H}_{3}})}_{2}}NH+C{{H}_{3}}COOH\]

    D) \[{{(C{{H}_{3}})}_{2}}NCOOH+C{{H}_{4}}\]

    Correct Answer: C

    Solution :

    \[{{(C{{H}_{3}})}_{2}}NCOC{{H}_{3}}\]on refluxing with acid gives dimethylamine and acetic acid. \[{{(C{{H}_{3}})}_{2}}\underset{\begin{smallmatrix}   \\  H \end{smallmatrix}}{\mathop{N}}\,-\underset{\begin{smallmatrix}   \\  OH \end{smallmatrix}}{\mathop{CO}}\,C{{H}_{3}}\xrightarrow[{}]{Acid}{{(C{{H}_{3}})}_{2}}NH\]        \[+C{{H}_{3}}COOH\]
