Inorganic derivatives of ammonia are also called amines, such as monochloramine (NClH2). [5] The substituent −NH2 is called an amino group. [6] The chemical notation for amines contains the letter "R", where "R" is not an element, but an "R-group", which in amines could be a single hydrogen or carbon atom, or could be a hydrocarbon chain.

Hydroxylamine (also known as hydroxyammonia) is an inorganic compound with the chemical formula N H 2 O H. The compound exists as hygroscopic colorless crystals. [4] . Hydroxylamine is almost always provided and used as an aqueous solution or more often as one of its salts such as hydroxylammonium sulfate, a water-soluble solid.
