Aldol condensation reaction:

Condensation between aldehyde and ketone molecule to form a {eq}{\rm{\beta }} {/eq}- hydroxy ketone/aldehyde is known as Aldol condensation. It is possible only for the carbonyl compound containing {eq}{\rm{\alpha }} {/eq}- hydrogen atom.

A reaction that causes a carbon-carbon bond and a enol or enolate molecule to form and reacts with an aldehyde or ketone is called an aldol condensation. Learn more about aldol condensation reactions and how it occurs in three steps: getting rid of the alpha hydrogen, forming new carbon and carbonyl bonds, and converting carbonyl groups to COH.
