Aldol reaction

Vedclass · Answer

(B) Aldehydes and ketones containing at least one $\alpha-H$ atom undergo a reaction in the presence of dilute alkali ($NaOH$ or $KOH$) to form $\beta-$hydroxy aldehydes (aldol) or $\beta-$hydroxy ketones (ketol). This reaction is known as the Aldol reaction. When this product is heated,it undergoes dehydration to form $\alpha, \beta-$unsaturated carbonyl compounds,which is known as Aldol condensation. Since the question describes the formation of the $\beta-$hydroxy product,it is specifically referred to as the Aldol reaction.

An aldehyde or ketone containing at least one $\alpha-H$ atom reacts with dilute $NaOH$ to form a $\beta-$hydroxy aldehyde or $\beta-$hydroxy ketone. This reaction is known as $—$
