    Identify C in the following reaction\[{{C}_{2}}{{H}_{2}}\xrightarrow[acid]{Chromic}A\xrightarrow{N{{H}_{3}}}B\xrightarrow[-{{H}_{2}}O]{\Delta }C\]

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

    B)  \[C{{H}_{3}}-CN\]

    C)  \[C{{H}_{3}}-C{{H}_{2}}-NH-C{{H}_{3}}\]

    D)  \[C{{H}_{3}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-N{{H}_{2}}\]

    Correct Answer: D

    Solution :

                     \[HC\equiv CH\xrightarrow[acid]{Chromic}\underset{\begin{smallmatrix}  \,\,\,\,\,\,\,\,\,\,(A) \\  acetic\,acid \end{smallmatrix}}{\mathop{C{{H}_{3}}COOH}}\,\xrightarrow{N{{H}_{3}}}\] \[\underset{\begin{smallmatrix}  \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\text{(B)} \\  \text{ammonium}\,\text{acetate} \end{smallmatrix}}{\mathop{C{{H}_{3}}COON{{H}_{4}}}}\,\xrightarrow[-{{H}_{2}}O]{\Delta }C{{H}_{3}}-\underset{\text{acetmide}}{\overset{O}{\mathop{\underset{(C)}{\overset{||}{\mathop{C}}}\,}}}\,-N{{H}_{2}}\]
