Purpose of aldol condensation

WebThus, this addition product is known as an aldol. The chemical reaction is called aldol condensation, in which a complex molecule is formed by joining two simple molecules. Aldol condensation can occur between 2 aldehyde molecules or an aldehyde and a ketone each possessing an alpha hydrogen. It can be both acid-catalyzed or base-catalyzed.
