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atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group [4] (these may respectively be called alkylamines ...
A series of linked nitrogen atoms is known as the nitrogen skeleton or nitrogen backbone. The number of nitrogen atoms is used to define the size of the azane (e.g. N 2-azane). The simplest possible azane (the parent molecule) is ammonia, NH 3. There is no limit to the number of nitrogen atoms that can be linked together, the only limitation ...
3 Ca + N 2 → Ca 3 N 2 3 Mg + 2 NH 3 → Mg 3 N 2 + 3 H 2 (at 900 °C) 3 Zn(NH 2) 2 → Zn 3 N 2 + 4 NH 3. Many variants on these processes are possible. The most ionic of these nitrides are those of the alkali metals and alkaline earth metals, Li 3 N (Na, K, Rb, and Cs do not form stable nitrides for steric reasons) and M 3 N 2 (M = Be, Mg ...
NH2. NH2 or similar may refer to: Azanide (chemical formula NH−2) Amino radical (chemical formula NH•2) Nitrenium ion (chemical formula NH+2) Primary amide group (chemical formula -NH2) National Harbor–Alexandria Line (Route NH2), a WMATA bus line between Alexandria, Virginia and Prince George's County, Maryland. National Highway 2 (India)
A cobalt (III) complex of aminomethyl is known in the form [Co (bipyridine) 2 (CH 2 NH 2)] (ClO4) 2. [1] Aminomethyl is the first member of a series of 1-aminoalkyl groups of the form − (CH2−)nNH2. [2] Aminomethyl is used in the standard (IUPAC) names of some compounds, [3] such as 4- (aminomethyl) benzoic acid.
Stock nomenclature for inorganic compounds is based on the indication of the oxidation number (as a roman numeral, in parentheses) of each of the major elements in the compound, e.g. iron (III) chloride. It is widely, if sometimes incorrectly, used on Wikipedia for the titles of articles about inorganic compounds.
