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)−NR 2.
Sodium amide, commonly called sodamide (systematic name sodium azanide), is the inorganic compound with the formula NaNH 2.It is a salt composed of the sodium cation and the azanide anion.
Thiourea (/ ˌ θ aɪ. oʊ j ʊəˈr iː. ə,-ˈ jʊər i-/) [2] [3] [4] is an organosulfur compound with the formula SC(NH 2) 2 and the structure H 2 N−C(=S)−NH 2.It is structurally similar to urea (H 2 N−C(=O)−NH 2), except that the oxygen atom is replaced by a sulfur atom (as implied by the thio-prefix); however, the properties of urea and thiourea differ significantly.
The structure of the molecule of urea is O=C(−NH 2) 2.The urea molecule is planar when in a solid crystal because of sp 2 hybridization of the N orbitals. [8] [9] It is non-planar with C 2 symmetry when in the gas phase [10] or in aqueous solution, [9] with C–N–H and H–N–H bond angles that are intermediate between the trigonal planar angle of 120° and the tetrahedral angle of 109.5°.
Nitric acid, with a pK value of around −1.7, behaves as a strong acid in aqueous solutions with a pH greater than 1. [23] At lower pH values it behaves as a weak acid. pK a values for strong acids have been estimated by theoretical means. [24] For example, the pK a value of aqueous HCl has been estimated as −9.3.
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)
Acetamide (systematic name: ethanamide) is an organic compound with the formula CH 3 CONH 2.It is an amide derived from ammonia and acetic acid.It finds some use as a plasticizer and as an industrial solvent. [5]
The σ values displayed in the Table above reveal certain substituent effects. With ρ = 1, the group of substituents with increasing positive values—notably cyano and nitro —cause the equilibrium constant to increase compared to the hydrogen reference, meaning that the acidity of the carboxylic acid (depicted on the left of the equation ...
