Thermal decarboxylation usually yields saturated products or ketones, but one specific class of subs — Aldehydes Ketones and Carboxylic Acids Chemistry Question

💡 Solution & Explanation

While gem-dicarboxylic acids and $\beta$ -keto acids decarboxylate to form alkanes/ketones respectively, $\beta,\gamma$ -unsaturated acids uniquely undergo decarboxylation on heating to yield alkenes via a concerted mechanism.
