उत्तर
Explanation:
Aldehydes and ketones with at least one α-hydrogen undergo a reaction in the presence of dilute alkali as a catalyst to create β-hydroxy aldehydes (aldol) or β-hydroxy ketones (ketol), respectively. This is known as an Aldol reaction.
Due to the lack of α-hydrogen, benzaldehyde does not undergo aldol reaction.
