    Among the following the order of reactivity towards nucieophilic addition is   JEE Main Online Paper (Held On 07 May 2012)

    A) \[C{{H}_{3}}CHO>C{{H}_{3}}COC{{H}_{3}}>HCHO\]

    B)                        \[HCHO>C{{H}_{3}}CHO>C{{H}_{3}}COC{{H}_{3}}\]

    C)                        \[C{{H}_{3}}CHO>HCHO>C{{H}_{3}}COC{{H}_{3}}\]

    D)                        \[C{{H}_{3}}COC{{H}_{3}}>C{{H}_{3}}CHO>HCHO\]

    Correct Answer: B

    Solution :

                    Presence of alkyl group in carbonyl compounds decreases their reactivity towards nucleophilic addition. Further greater the number of such groups lesser will be the reactivity towards nucleophilic addition  \[\therefore \]correct order is
