In chemistry, the amino radical, ·NH 2, 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.
Hydrazine is an inorganic compound with the chemical formula N 2 H 4.It is a simple pnictogen hydride, and is a colourless flammable liquid with an ammonia-like odour.Hydrazine is highly hazardous unless handled in solution as, for example, hydrazine hydrate (N 2 H 4 ·xH 2 O).
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 -NH
Pigment Yellow 97, a popular yellow colorant, is a hydrazone. [6]Hydrazones are the basis for various analyses of ketones and aldehydes. For example, dinitrophenylhydrazine coated onto a silica sorbent is the basis of an adsorption cartridge.
In the common names of such salts, the cation is often called "hydrazine", as in "hydrazine sulfate" for hydrazinium hydrogensulfate. The terms "hydrazinium" and "hydrazine" may also be used for the doubly protonated cation [N 2 H 6] 2+, more properly called hydrazinediium or hydrazinium(2+). This cation has an ethane-like structure ([H 3 N− ...
The Wolff–Kishner reduction is a reaction used in organic chemistry to convert carbonyl functionalities into methylene groups. [1] [2] In the context of complex molecule synthesis, it is most frequently employed to remove a carbonyl group after it has served its synthetic purpose of activating an intermediate in a preceding step.
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(NH 3 (in which the bond angle between the nitrogen and hydrogen is 107°), wherein one or more hydrogen atoms have been replaced by a substituent such as an ...
A general linear imide functional group. 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.
