In chemistry, a hydroxy or hydroxyl group is a functional group with the chemical formula −OH and composed of one oxygen atom covalently bonded to one hydrogen atom. In organic chemistry , alcohols and carboxylic acids contain one or more hydroxy groups.
L n M(OH 2) + B ⇌ L n M(OH) – + BH + (L = ligand, B = base) Vanadic acid H 3 VO 4 shows similarities with phosphoric acid H 3 PO 4 though it has a much more complex vanadate oxoanion chemistry. Chromic acid H 2 CrO 4, has similarities with sulfuric acid H 2 SO 4; for example, both form acid salts A + [HMO 4] −. Some metals, e.g. V, Cr, Nb ...
When necessary, the position of the hydroxyl group is indicated by a number between the alkane name and the -ol: propan-1-ol for CH 3 CH 2 CH 2 OH, propan-2-ol for CH 3 CH(OH)CH 3. If a higher priority group is present (such as an aldehyde, ketone, or carboxylic acid), then the prefix hydroxy-is used, [19] e.g., as in 1-hydroxy-2-propanone (CH ...
Hydroxylamine (also known as hydroxyammonia) is an inorganic compound with the chemical formula N H 2 OH.The compound exists as hygroscopic colorless crystals. [4] Hydroxylamine is almost always provided and used as an aqueous solution or more often as one of its salts such as hydroxylammonium sulfate, a water-soluble solid.
A strong base is a basic chemical compound that can remove a proton (H +) from (or deprotonate) a molecule of even a very weak acid (such as water) in an acid–base reaction. Common examples of strong bases include hydroxides of alkali metals and alkaline earth metals, like NaOH and Ca(OH)
The hydroxyl radical can damage virtually all types of macromolecules: carbohydrates, nucleic acids , lipids (lipid peroxidation) and amino acids (e.g. conversion of Phe to m-Tyrosine and o-Tyrosine). The hydroxyl radical has a very short in vivo half-life of approximately 10 −9 seconds and a high reactivity. [5]
An ester of a carboxylic acid.R stands for any group (typically hydrogen or organyl) and R ′ stands for any organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (R ′). [1]
Hydroxylammonium chloride is a chemical compound with the formula [NH 3 OH] + Cl −.It is the hydrochloric acid salt of hydroxylamine (NH 2 OH).Hydroxylamine is a biological intermediate in nitrification (biological oxidation of ammonia with oxygen into nitrite) and in anammox (biological oxidation of nitrite and ammonium into dinitrogen gas) which are important in the nitrogen cycle in soil ...
