:''This article is about the hydroxyl functional group. For the Hydroxyl radical see [[Hydroxyl radical]].''
'''Hydroxyl''' in [[chemistry]] stands for a molecule consisting of an [[oxygen]] atom and a [[hydrogen]] atom connected by a [[covalent bond]]. The neutral form is a hydroxyl [[Radical (chemistry)|radical]] and the hydroxyl [[anion]] is called a [[hydroxide]]. When the oxygen atom is linked to a larger molecule the hydroxyl group is a [[functional group]] ('''HO¯''' or '''¯OH''') . Hydroxide (OH anion) is a polyatomic ion with a charge of negative one. Hydroxide anion is a base and is used to make solutions or compounds basic.
==Hydroxyl group==<!-- This section is linked from [[Silane]] -->
The term '''hydroxyl group''' is used to describe the [[functional group]] –OH when it is a [[substituent]] in an [[organic compound]]. Organic molecules containing a hydroxyl group are known as [[alcohol]]s (the simplest of which have the formula [[Alkyl|C<sub>n</sub>H<sub>2n+1</sub>]]–'''OH''').
==Hydroxyl radical==
{{main|Hydroxyl radical}}
The hydroxyl radical, ·OH, is the neutral form of the '''hydroxide''' ion. '''Hydroxyl radicals''' are highly reactive and, as a consequence, short-lived; however, they form an important part of [[Radical (chemistry)|radical chemistry]].
