  • question_answer With a change in hybridisation of the carbon bearing the charge, the stability of a carbanion increase in the order [DCE 2003]

    A) \[sp<s{{p}^{2}}<s{{p}^{3}}\]

    B) \[sp<s{{p}^{3}}<s{{p}^{2}}\]

    C) \[s{{p}^{3}}<s{{p}^{2}}<sp\]

    D) \[s{{p}^{2}}<sp<s{{p}^{3}}\]

    Correct Answer: C

    Solution :

    Stability of carbanions increase with increase in s-character of hybrid orbitals of carbon bearing charge, hence correct order is : \[s{{p}^{3}}<s{{p}^{2}}<sp\].
