stability order of carbanions

Vedclass · Answer

(A) Hyperconjugation involves the delocalization of electrons from a $\sigma$ $C-H$ bond of an $sp^3$ hybridized carbon into an adjacent vacant $p$-orbital (in carbocations),a half-filled $p$-orbital (in free radicals),or a $\pi$-bond (in alkenes). This interaction provides stability to these species. Carbanions possess a lone pair of electrons on a carbon atom and do not have a vacant or half-filled $p$-orbital adjacent to the $C-H$ bond to facilitate this type of electron delocalization. Therefore,the stability order of carbanions is not explained by hyperconjugation.
