WebAldehydes and ketones react with primary amines to form a class of compounds called imines. The mechanism for imine formation proceeds through the following steps: 1. An unshared pair of electrons on the nitrogen of the amine is attracted to the partial‐positive carbon of the carbonyl group. 2. WebAldol condensation of same type aldehyde or ketone. Aldehyde or ketone which has alpha hydrogen reacts with any strong bases such as NaOH, KOH and Ba (OH) 2 and give aldol as the product. This reaction doubles the number of carbon atoms of initial aldehyde or ketone. To dehydrate the aldol compound, it is heated alone or with I 2.
