Nitrous acid (molecular formula H N O 2) is a weak and monoprotic acid known only in solution, in the gas phase, and in the form of nitrite (NO − 2) salts. [3] It was discovered by Carl Wilhelm Scheele, who called it "phlogisticated acid of niter". Nitrous acid is used to make diazonium salts from amines.
The structure of an organic nitro compound. In organic chemistry, nitro compounds are organic compounds that contain one or more nitro functional groups (−NO 2).The nitro group is one of the most common explosophores (functional group that makes a compound explosive) used globally.
Nitroxylic acid or hydronitrous acid is an unstable reduced oxonitrogen acid. It has formula H 4 N 2 O 4 containing nitrogen in the +2 oxidation state. [1] It consists of a central pair of bonded nitrogen atoms with four hydroxyl groups around them, giving rise to hydrazine-1,1,2,2-tetrol as an alternate chemical name.
Nitrous oxide (dinitrogen oxide or dinitrogen monoxide), commonly known as laughing gas, nitrous, or factitious air, among others, [4] is a chemical compound, an oxide of nitrogen with the formula N 2 O. At room temperature, it is a colourless non-flammable gas, and has a slightly sweet scent and taste. [4]
NO y is the class of compounds comprising NO x and the NO z compounds produced from the oxidation of NO x which include nitric acid, nitrous acid (HONO), dinitrogen pentoxide (N 2 O 5), peroxyacetyl nitrate (PAN), alkyl nitrates (RONO 2), peroxyalkyl nitrates (ROONO 2), the nitrate radical (NO 3), and peroxynitric acid (HNO 4).
Nitric acid is an inorganic compound with the formula H N O 3. ... nitric acid is used as a chemical doping agent for organic semiconductors, ...
The nitrite ion has the chemical formula NO − 2. Nitrite (mostly sodium nitrite) is widely used throughout chemical and pharmaceutical industries. [1] The nitrite anion is a pervasive intermediate in the nitrogen cycle in nature. The name nitrite also refers to organic compounds having the –ONO group, which are esters of nitrous acid.
There are two possible structures of hyponitrous acid, trans and cis.trans-Hyponitrous acid forms white crystals that are explosive when dry.In aqueous solution, it is a weak acid (pK a1 = 7.21, pK a2 = 11.54), [2] and decomposes to nitrous oxide and water with a half life of 16 days at 25 °C at pH 1–3:
