The dry distillation of the calcium salt of a specific aliphatic dicarboxylic acid yields cyclopenta — Aldehydes Ketones and Carboxylic Acids Chemistry Question

💡 Solution & Explanation

Calcium salts of dicarboxylic acids undergo dry distillation to produce 5- or 6-membered cyclic ketones. Adipic acid ($C_6H_{10}O_4$) forms a calcium salt that loses $CaCO_3$ upon heating to form the 5-membered cyclic ketone, cyclopentanone.
