  • question_answer Which of the following is an electrophile [J & K 2005]

    A) \[{{H}_{2}}O\]

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

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

    D) \[ROR\]

    Correct Answer: B

    Solution :

     \[H-\overset{\bullet \,\,\bullet }{\mathop{\underset{\bullet \,\,\bullet }{\mathop{O}}\,}}\,-H,\,\,:N{{H}_{3}},\,\,R-\overset{\bullet \,\,\bullet }{\mathop{\underset{\bullet \,\,\bullet }{\mathop{O}}\,}}\,-R\]- nucleophiles \[S{{O}_{3}}\] has electron deficient centre (a reagent which can accept an electron pair in a reaction, is called an electrophile)
