    Identify \[X\] and \[Y\] in the following sequence \[{{C}_{2}}{{H}_{5}}Br\xrightarrow{X}\text{product}\xrightarrow{\text{Y}}{{C}_{3}}{{H}_{7}}N{{H}_{2}}\] [Orissa JEE 2005]

    A) \[X=KCN,\,Y=LiAl{{H}_{4}}\]

    B) \[X=KCN,\,Y={{H}_{3}}{{O}^{+}}\]

    C) \[X=C{{H}_{3}}Cl,\,Y=AlC{{l}_{3}}/HCl\]

    D) \[X=C{{H}_{3}}N{{H}_{2}},Y=HN{{O}_{2}}\]

    Correct Answer: A

    Solution :

    \[{{C}_{2}}{{H}_{5}}Br\xrightarrow{KCN(X)}{{C}_{2}}{{H}_{5}}CN\xrightarrow{LiAl{{H}_{4}}(Y)}\]\[{{C}_{2}}{{H}_{5}}C{{H}_{2}}N{{H}_{2}}({{C}_{3}}{{H}_{7}}N{{H}_{2}})\] \[X=KCN,\,Y=LiAl{{H}_{4}}\]
