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 ...

2024年11月20日 · Azanide is a nitrogen hydride and a monovalent inorganic anion. It is a conjugate base of an ammonia. It is a conjugate acid of a hydridonitrate (2-).

The National Institute of Standards and Technology (NIST) uses its best efforts to deliver a high quality copy of the Database and to verify that the data contained therein have been selected on the basis of sound scientific judgment.

2021年7月30日 · The NH2– ion comprises a central Nitrogen atom bonded to two hydrogen atoms. Single bonds are formed between Nitrogen and Hydrogen. There are also two lone pairs attached to the Nitrogen atom. The hybridization of the Azanide ion is sp3. NH2– has a Bent molecular structure and a tetrahedral electronic shape. This results in bond angles of ...

2020年11月10日 · In this article, we will discuss NH2- molecular geometry and Lewis structure of NH2- along with its shape, bond angle, polarity, hybridization, and other chemical and molecular properties.

2011年7月29日 · The NH2- anion is the conjugate base of ammonia (NH 3). If you’ll recall, the weaker the acid, the stronger the conjugate base – and since NH 3 has a pKa of 38, NH 2 is a strong base indeed.

2023年10月11日 · The Lewis structure of the azanide [NH2]– ion consists of a nitrogen (N) atom at the center. It is bonded to two atoms of hydrogen (H) at the sides. There are a total of 4 electron density regions around the central N-atom in [NH2]– lewis structure.

2016年5月21日 · If two similar sized atoms have different electronegativity values, the atom with higher electronegativity holds the electrons more tightly, and thus is more stable. Example: hydroxide vs azanide (NH2-). If two atoms have different sizes (down the periodic table), the larger atom has electrons more spread out and thus is more stable.

NH 2 (amino) bonded phase has strong polar adsorption in non-polar organic solvents, with weak anion exchange retention. NH2 SPE cartridge ‘s effect with anions is weaker than SAX SPE cartridge. NH 2 excels in a variety of sample matrices for use in food, environmental, pharmaceutical, and medical applications.

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.
