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atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group [4] (these may respectively be called alkylamines ...
Methanediamine is the simplest diamine.Its chemical formula is CH 2 (NH 2) 2, and its structure consists of two amino groups on a central carbon atom. Although methanediamine it only exists transiently in solution, [2] its hydrochloride salt has been used in chemical synthesis since 1914. [3]
H 2 + NH 2 → NH 3 + H. has a rate constant of 2.2 × 10 −15. Assuming H 2 densities of 10 5 and [NH 2]/[H 2] ratio of 10 −7, this reaction proceeds at a rate of 2.2 × 10 −12, more than three orders of magnitude slower than the primary reaction above. Some of the other possible formation reactions are: H − + [NH 4] + → NH 3 + H 2 ...
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 ...
Chemical structure. A chemical structure of a molecule is a spatial arrangement of its atoms and their chemical bonds. Its determination includes a chemist 's specifying the molecular geometry and, when feasible and necessary, the electronic structure of the target molecule or other solid. Molecular geometry refers to the spatial arrangement of ...
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.
