This article is about the hydroxyl functional group. For the Hydroxyl radical see Hydroxyl radical. Hydroxyl in Chemistry describes a molecule consisting of an Oxygen atom and a Hydrogen atom joined by a Covalent bond.

Hydroxyl in chemistry stands for a molecule consisting of an oxygen atom and a hydrogen atom connected by a covalent bond. Chemistry (from Egyptian kēme (chem meaning "earth") is the Science concerned with the composition structure and properties Oxygen (from the Greek roots ὀξύς (oxys (acid literally "sharp" from the taste of acids and -γενής (-genēs (producer literally begetteris the Hydrogen (ˈhaɪdrədʒən is the Chemical element with Atomic number 1 The neutral form is a hydroxyl radical and the hydroxyl anion is called a hydroxide. In Chemistry, radicals (often referred to as free radicals) are atoms molecules or ions with Unpaired electrons on an otherwise Open shell An ion is an Atom or Molecule which has lost or gained one or more Valence electrons giving it a positive or negative electrical charge In Chemistry, hydroxide is the most common name for the diatomic Anion OH− consisting of Oxygen and Hydrogen When the oxygen atom is linked to a larger molecule the hydroxyl group is a functional group (HO¯ or ¯OH) . In Organic chemistry, functional groups are specific groups of Atoms within Molecules that are responsible for the characteristic Chemical reactions

Hydroxyl group

The term hydroxyl group is used to describe the functional group –OH when it is a substituent in an organic compound. In Organic chemistry, functional groups are specific groups of Atoms within Molecules that are responsible for the characteristic Chemical reactions In Organic chemistry, a substituent is an atom or group of atoms substituted in place of a Hydrogen atom on the Parent chain of a Hydrocarbon An organic compound is any member of a large class of Chemical compounds whose Molecules contain Carbon. Organic molecules containing a hydroxyl group are known as alcohols (the simplest of which have the formula C_nH_2n+1–OH). In Chemistry, an alcohol is any Organic compound in which a Hydroxyl group ( - O[[hydrogen H]]) is bound to a Carbon An alkyl is a Univalent radical consisting of Carbon and Hydrogen atoms arranged in a chain

Hydroxyl radical

Main article: Hydroxyl radical

The hydroxyl radical, ·OH, is the neutral form of the hydroxide ion. Hydroxyl in Chemistry describes a molecule consisting of an Oxygen atom and a Hydrogen atom joined by a Covalent bond. Hydroxyl radicals are highly reactive and, as a consequence, short-lived; however, they form an important part of radical chemistry. In Chemistry, radicals (often referred to as free radicals) are atoms molecules or ions with Unpaired electrons on an otherwise Open shell
