  • question_answer
    Arrange the following in the increasing order of reactivity with \[N{{H}_{3}}\]:
    (I) \[C{{H}_{2}}O\]
    (II) \[C{{H}_{3}}CHO\]
    (III) \[C{{H}_{3}}-CO-C{{H}_{3}}\]
    (IV)

    A) I<II<III<IV      

    B) III<IV<I<II

    C) IV<III<II<I      

    D) II<I<IV<III

    Correct Answer: C

    Solution :

    [c] Reactivity follows the ease with which a nucleophile can attack at carbonyl carbon. Greater the steric hindrance at carbonyl carbon, smaller the reactivity.
