$A$ is more stable than $B$

Vedclass · Answer

(A) The enolate formed from $A$ (cyclohexane$-1,3-$dione) is significantly more stable than the enolate formed from $B$ (cyclohexane$-1,4-$dione).In the enolate of $A$,the negative charge is delocalized over two carbonyl groups via resonance ($-M$ effect),which provides extra stabilization.In the enolate of $B$,the negative charge is delocalized over only one carbonyl group,as the other carbonyl group is too far away to participate in the resonance stabilization of the carbanion.Therefore,the enolate of $A$ is more stable.
