    Identify the product Z  in the series \[C{{H}_{3}}CN\xrightarrow{Na+{{C}_{2}}{{H}_{5}}OH}X\xrightarrow{HN{{O}_{2}}}Y\underset{{{H}_{2}}S{{O}_{4}}}{\mathop{\xrightarrow{{{K}_{2}}C{{r}_{2}}{{O}_{7}}}}}\,Z\] [AIIMS 1983; JIPMER 2001]

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

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

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

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

    Correct Answer: C

    Solution :

               \[C{{H}_{3}}-C\equiv N\underset{\text{Reduction}}{\mathop{\xrightarrow{Na+EtOH}}}\,C{{H}_{3}}-C{{H}_{2}}-N{{H}_{2}}\]                                     \[\xrightarrow{HN{{O}_{2}}}C{{H}_{3}}C{{H}_{2}}-OH\underset{{{H}_{2}}S{{O}_{4}}}{\mathop{\xrightarrow{{{K}_{2}}C{{r}_{2}}{{O}_{7}}}}}\,C{{H}_{3}}COOH\]
