  • question_answer
    Arrange the following carbanions in decreasing order of stability.

    A) IV>III>I>II     

    B) III>IV>II>I

    C)  I>III>II>IV                 

    D)  II>I>III>IV

    Correct Answer: A

    Solution :

    [a] \[-N{{O}_{2}}\] Has greater electron withdrawing power than \[-CN\]by resonance effect, hence IV is most stable followed by III. II is least stable as delocalization of negative charge is opposed by electron donating resonance effect of methoxy group.
