    \[C{{H}_{3}}COOH\xrightarrow{N{{H}_{3}}}\xrightarrow{\Delta }?\] The product of the reaction is isomeric with

    A) \[\underset{\begin{smallmatrix}  | \\  N{{H}_{2}} \end{smallmatrix}}{\mathop{C{{H}_{2}}}}\,-CHO\]                          

    B)                        \[C{{H}_{3}}CH=NOH\]

    C)                        \[HCONH-C{{H}_{3}}\]  

    D)                         All of these

    Correct Answer: C

    Solution :

    \[\underset{acetic\,acid}{\mathop{C{{H}_{3}}COOH}}\,\xrightarrow{N{{H}_{3}}}C{{H}_{3}}COON{{H}_{4}}\xrightarrow[-{{H}_{2}}O]{\Delta }\]                                                 \[C{{H}_{3}}CO\]   \[\underset{acetamide}{\mathop{N{{H}_{2}}}}\,\] The isomers of\[C{{H}_{3}}CON{{H}_{2}}\]are \[\underset{(I)}{\mathop{N{{H}_{2}}C{{H}_{2}}CHO}}\,,\,\,C{{H}_{3}}-\underset{(II)}{\mathop{CH}}\,=NOH\]                 \[H-\underset{(III)}{\mathop{CONH}}\,-C{{H}_{3}}\]
