Amines

Organic compounds and functional groups which contain a basic nitrogen atom with a lone pair are known as Amines. Amines are derivatives of ammonia, in which one or more hydrogen atoms have been replaced via a substituent like an alkyl or aryl group. Significant amines include amino acids, trimethylamine, biogenic amines, and aniline. Inorganic derivatives of ammonia are as well called amines, like chloramine (NClH₂).
