what is amine

An amine is a functional group in chemistry that contains a basic nitrogen atom with a lone pair. Amines are formally derivatives of ammonia (NH3), where one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group. Amines can be classified according to the number of carbon atoms bonded directly to the nitrogen atom. A primary (1°) amine has one alkyl (or aryl) group on the nitrogen atom, a secondary (2°) amine has two, and a tertiary (3°) amine has three/15%3A_Organic_Acids_and_Bases_and_Some_of_Their_Derivatives/15.10%3A_Amines_-_Structures_and_Names). Amines are named in several ways, including the prefix "amino-" or the suffix "-amine". Amino acids, biogenic amines, trimethylamine, and aniline are important examples of amines. Amines have a wide range of applications, including in the production of amino acids, water purification, medicine manufacturing, and the development of insecticides and pesticides.
