What are the similarities between amine and amide?

Both amines and amides contain a nitrogen atom in their structure. In amines, the nitrogen atom is directly bonded to carbon atoms (alkyl or aryl groups), while in amides, the nitrogen atom is bonded to a carbonyl carbon atom. Additionally, both amines and amides are derived from ammonia molecules, where one or more hydrogen atoms are replaced by organic substituents. Another similarity is that they have distinct functional groups. Amines have an amino group (–NH2), while amides have an amide group (–CONH2).
