The dry distillation of the calcium salt of Adipic acid (Hexanedioic acid) forces an intramolecular — Aldehydes Ketones and Carboxylic Acids Chemistry Question

💡 Solution & Explanation

Adipic acid ($HOOC-(CH_2)_4-COOH$) is a 6-carbon dicarboxylic acid. When its calcium salt undergoes dry distillation, one carbon is lost as part of the $CaCO_3$ leaving group. The remaining 5 carbons form a stable 5-membered cyclic ketone known as Cyclopentanone.
