    \[{{C}_{2}}{{H}_{5}}Cl+KCN\xrightarrow{{}}X\xrightarrow{\text{Hydrolysis}}Y.\] 'X' and 'Y' are [MP PET 1995]

    A) \[{{C}_{2}}{{H}_{6}}\] and \[{{C}_{2}}{{H}_{5}}CN\]

    B) \[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}OH,\] and \[C{{H}_{3}}-CHOH-C{{H}_{3}}\]

    C) \[C{{H}_{3}}-C(C{{H}_{3}})(OH)-C{{H}_{3}}\] and \[{{C}_{2}}{{H}_{5}}C{{H}_{2}}N{{H}_{2}}\]

    D) \[{{C}_{2}}{{H}_{5}}CN\] and \[{{C}_{2}}{{H}_{5}}COOH\]

    Correct Answer: D

    Solution :

     \[{{C}_{2}}{{H}_{5}}Cl+KCN\to \underset{(X)}{\mathop{\underset{\text{Ethyl}\,\,\text{cyanide}}{\mathop{{{C}_{2}}{{H}_{5}}CN}}\,}}\,\xrightarrow{\text{Hydrolysis}}\underset{(Y)}{\mathop{\underset{\text{Propanoic}\,\,\text{acid}}{\mathop{{{C}_{2}}{{H}_{5}}COOH}}\,}}\,\]
