Vedclass · Answer

(B) Decarboxylation of $\beta$-keto acids occurs readily because the transition state is stabilized by the formation of an enol intermediate,which is further stabilized by the electron-withdrawing effect of the carbonyl group. Among the given options,$2$-oxocyclohexane-$1$-carboxylic acid (option $B$) is a $\beta$-keto acid. The decarboxylation process involves the formation of a cyclic six-membered transition state,which is highly favorable. The electron-withdrawing $-I$ and $-M$ effects of the ketone carbonyl group stabilize the developing negative charge on the $\alpha$-carbon during the transition state,making it the most reactive compound for decarboxylation under mild conditions.

The compound that undergoes decarboxylation most readily under mild conditions is:
