WebMar 15, 2024 · In amines, nitrogen is bonded to three other atoms (alkyl groups or hydrogens) and has a lone pair of nonbonding electrons. This lone pair produces a … In chemistry, amines are compounds and functional groups that contain a basic nitrogen atom with a lone pair. Amines are formally derivatives of ammonia (NH3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group (these may respectively be called alkylamines … See more Amines can be classified according to the nature and number of substituents on nitrogen. Aliphatic amines contain only H and alkyl substituents. Aromatic amines have the nitrogen atom connected to an aromatic See more Alkyl amines Alkyl amines characteristically feature tetrahedral nitrogen centers.
