    The species which acts as both nucleophile and electrophile is

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

    B)  \[N{{H}_{3}}\]

    C)  \[P{{(C{{H}_{3}})}_{2}}\]

    D)  \[{{H}_{2}}\]

    Correct Answer: A

    Solution :

     Those compounds in which the carbon atom is attached with strongly electronegative element (like N or O) by \[\pi \] bond, generally act as both electrophile and nucleophile. e.g., \[C{{H}_{3}}-\overset{\pi \,bond}{\mathop{C}}\,\equiv N\leftarrow \text{strongly}\,\text{electronegative}\]
