In chemistry, the amino radical, ·NH2, also known as the aminyl or azanyl, is the neutral form of the amide ion (NH− 2). Aminyl radicals are highly reactive and consequently short-lived, like most radicals; however, they form an important part of nitrogen chemistry. In sufficiently high concentration, amino radicals dimerise to form hydrazine.
Azanide is the IUPAC -sanctioned name for the anion NH− 2. The term is obscure; derivatives of NH− 2 are almost invariably referred to as amides, [1][2][3] despite the fact that amide also refers to the organic functional group – C (=O)−NR2. The anion NH− 2 is the conjugate base of ammonia, so it is formed by the self-ionization of ...
Amine. In chemistry, amines (/ ə ˈ m iː n, ˈ æ m iː n /, [1] [2] UK also / ˈ eɪ m iː n / [3]) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group [4] (these may respectively be called alkylamines ...
Hydroxylamine (also known as hydroxyammonia) is an inorganic compound with the chemical formula N H 2 O H. The compound is in a form of a white hygroscopic crystals. [4] Hydroxylamine is almost always provided and used as an aqueous solution. It is consumed almost exclusively to produce Nylon-6.
Imide. In organic chemistry, an imide is a functional group consisting of two acyl groups bound to nitrogen. [1] The compounds are structurally related to acid anhydrides, although imides are more resistant to hydrolysis. In terms of commercial applications, imides are best known as components of high-strength polymers, called polyimides.
Carbamic acid is a planar molecule. [3]The H 2 N− group of carbamic acid, unlike that of most amines, cannot be protonated to an ammonium group H 3 N + −.The zwitterionic form H 3 N + −COO − is very unstable and promptly decomposes into ammonia and carbon dioxide, [6] yet there is a report of its detection in ices irradiated with high-energy protons.
Aromatic amine. In organic chemistry, an aromatic amine is an organic compound consisting of an aromatic ring attached to an amine. It is a broad class of compounds that encompasses anilines, but also many more complex aromatic rings and many amine substituents beyond NH2. Such compounds occur widely. [1] Representative aromatic amines.
