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.
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atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group [4] (these may respectively be called alkylamines ...
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 ...
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°.
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 ...
Nitrogen compounds. The chemical element nitrogen is one of the most abundant elements in the universe and can form many compounds. It can take several oxidation states; but the most common oxidation states are -3 and +3. Nitrogen can form nitride and nitrate ions. It also forms a part of nitric acid and nitrate salts.
A series of linked nitrogen atoms is known as the nitrogen skeleton or nitrogen backbone. The number of nitrogen atoms is used to define the size of the azane (e.g. N 2-azane). The simplest possible azane (the parent molecule) is ammonia, NH 3. There is no limit to the number of nitrogen atoms that can be linked together, the only limitation ...
Ammonium sulfate is made by treating ammonia with sulfuric acid: 2 NH3 + H2SO4 → (NH4)2SO4. A mixture of ammonia gas and water vapor is introduced into a reactor that contains a saturated solution of ammonium sulfate and about 2% to 4% of free sulfuric acid at 60 °C. Concentrated sulfuric acid is added to keep the solution acidic, and to ...
