Decarboxylation typically requires harsh conditions like soda lime () and heat. However, certain car — Aldehydes Ketones and Carboxylic Acids Chemistry Question

💡 Solution & Explanation

Gem-dicarboxylic acids, $\beta$ -keto acids, and $\beta,\gamma$ -unsaturated acids possess structural features that allow for stable, concerted transition states (often 6-membered), lowering the activation energy so they easily decarboxylate upon simple heating. Simple aliphatic acids require soda lime.
