    Which one of the following series contains electrophiles only?

    A)  \[{{H}_{2}}O,S{{O}_{3}},{{H}_{3}}{{O}^{+}}\]

    B)         \[N{{H}_{3}},{{H}_{2}}O,AlC{{l}_{3}}\]

    C)         \[AlC{{l}_{3}},S{{O}_{3}},\overset{+}{\mathop{N}}\,{{O}_{2}}\]

    D)         \[{{H}_{2}}O,\overset{+}{\mathop{C}}\,l,N{{H}_{3}}\]

    Correct Answer: C

    Solution :

    Electrophiles are electron deficient species. In other words, species having a tendency to accept electrons are called electrophiles. These may be neutral or positively charged, e.g., \[AgC{{l}_{3}},S{{O}_{3}},\overset{+}{\mathop{N}}\,{{O}_{2}}\]etc.
