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.

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 2) National Harbor–Alexandria Line (Route NH2), a WMATA bus line between Alexandria, Virginia and Prince George's County, Maryland; National Highway 2 (India)

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.

2020年11月10日 · NH2- is an incredibly strong conjugate base of NH3. It has a total of 8 valence electrons which are participated in the formation of the Lewis dot structure whereas there are 2 bonding pairs and 2 lone pairs of electrons within the molecule.

2021年7月30日 · What is the Azanide ion? NH2- is often confused with the organic amide group. This article on its Lewis Structure, geometry, and hybridization will help differentiate the two.

Imines can be hydrolyzed back to the corresponding 1 o amine under acidic conditions. A wide variety of substances with −NH 2 groups can react with aldehydes and ketones by an addition-elimination sequence to yield compounds with a carbon-nitrogen double bond.

2020年8月27日 · During an acid/base reaction the lone pair electrons attack an acidic hydrogen to form a N-H bond. This gives the nitrogen in the resulting ammonium salt four single bonds and a positive charge.
