Question
Explain aldol condensation with suitable example. ### Write a short note: Aldol condensation.

Answer

→ Aldol condensation: "Aldehydes and ketones having at least one a-hydrogen undergo a reaction in the presence of dilute alkali as catalyst to form ẞ-hydroxy aldehydes (aldol) or ẞ-hydroxy ketones (ketol), respectively. This is known as Aldol reaction."

→ The name aldol is derived from the names of the two functional groups, aldehyde and alcohol, present in the products. The aldol and ketol readily lose water to give $\alpha$, ẞ-unsaturated carbonyl compounds which are aldol condensation products and the reaction is called Aldol condensation. Though ketones give ketols (compounds containing a keto and alcohol groups), the general name aldol condensation still applies to the reactions of ketones due to their similarity with aldehydes.
