    Which of the following behaves both as a nucleophile and as an electrophile?

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

    B) \[C{{H}_{3}}OH\]

    C) \[C{{H}_{2}}=CHC{{H}_{3}}\]          

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

    Correct Answer: A

    Solution :

    [a] Due to the presence of a lone pair of electrons on N, \[C{{H}_{3}}C\equiv N:\] acts as a nucleophile. Further due to greater electronegativity of N than C, the C atom of \[-C\equiv N\] carries a positive charge and hence behaves as an electrophile.
