Vedclass · Answer

(A) Decarboxylation of $\beta$-keto acids is very easy because it proceeds through a stable six-membered cyclic transition state involving hydrogen bonding between the carboxylic acid hydrogen and the carbonyl oxygen. Among the given options,$CH_3CH_2COCH_2COOH$ (option $A$) is a $\beta$-keto acid,where the carbonyl group is at the $\beta$-position relative to the carboxylic acid group. This allows for the formation of the stable cyclic transition state,making it highly reactive towards decarboxylation upon heating. Other options do not possess a $\beta$-keto group.

Which of the following is most reactive for decarboxylation?
