Answer:
The key feature of an amine is a nitrogen atom bonded to a carbonyl carbon atom. Like esters, amides are formed in a condensation reaction. ... These polymers are formed from another organic nitrogen compound, the amino acid. These molecules contain both an amine group and a carboxyl group.
Answer: nitrogen
Explanation:
Functional groups are specific group of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.
1. Amides have functional group [tex]-O=C-NH_2[/tex].
Example: Ethanamide with molecular formula [tex]CH_3CONH_2[/tex]
2. Amines have functional group [tex]-NH_2[/tex].
Example: Ethanamine with molecular formula [tex]CH_3CH_2NH_2[/tex]
Thus both amines and amides are organic compounds containing the element nitrogen.
