    Identify the product C in the series\[C{{H}_{3}}CN\xrightarrow{Na/{{C}_{2}}{{H}_{5}}OH}A\xrightarrow{HN{{O}_{2}}}B\]\[\xrightarrow{\begin{smallmatrix}  Tollen's \\  reagent \end{smallmatrix}}C\]

    A) \[C{{H}_{3}}COOH\]  

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

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

    D) \[C{{H}_{3}}CHO\]

    Correct Answer: A

    Solution :

    \[\underset{\begin{smallmatrix}  methyl \\  cyanide \end{smallmatrix}}{\mathop{C{{H}_{3}}CN}}\,\xrightarrow[Na/{{C}_{2}}{{H}_{5}}OH]{4H}\underset{\begin{smallmatrix}  ethyl\,\text{amine} \\  \text{(A)} \end{smallmatrix}}{\mathop{C{{H}_{3}}C{{H}_{2}}N{{H}_{2}}}}\,\]\[\xrightarrow{HN{{O}_{2}}}\underset{(B)}{\mathop{\underset{ethyl\,alcohol}{\mathop{C{{H}_{3}}C{{H}_{2}}OH}}\,}}\,\xrightarrow{Tollen's\,\,reagent}\] \[C{{H}_{3}}CHO\xrightarrow{{}}\underset{(C)}{\mathop{\underset{acetic\,acid}{\mathop{C{{H}_{3}}COOH}}\,}}\,\]
