    Which of the following is an electrophile?

    A) \[{{H}_{2}}O\]         

    B) \[S{{O}_{3}}\]

    C) \[~N{{H}_{3}}\]         

    D) \[~ROR\]

    Correct Answer: B

    Solution :

     The species which are electron deficient and accept a pair of electron are called electrophile. Hence, \[\text{S}{{\text{O}}_{\text{3}}}\]is a electrophile as it contains an electron deficient centre. While \[{{\text{H}}_{\text{2}}}\text{O,}\,\text{N}{{\text{H}}_{\text{3}}}\]and \[R-O-R\]are nucleophiles.
