Hydroxyl 14386 221863477 2008-06-26T12:41:08Z 150.243.41.10 :''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]]. ==See also== {{Wiktionary}} *[[Hydronium]] *[[Oxide]] *[[Hydroxy]] [[Category:Hydroxides]] [[Category:Functional groups]] [[Category:Alcohols]] [[Category:Chemistry stubs]] {{organic-chem-stub}} [[ar:هيدروكسيل]] [[ca:Grup hidroxil]] [[cs:Hydroxyl]] [[de:Hydroxylgruppe]] [[es:Grupo hidroxilo]] [[eo:Hidroksila grupo]] [[fr:Hydroxyle]] [[id:Hidroksil]] [[is:Hýdroxýl]] [[it:Ione idrossido]] [[he:הידרוקסיל]] [[la:Hydroxydatum]] [[ja:ヒドロキシ基]] [[nds:Hydroxyl-Grupp]] [[pl:Grupa hydroksylowa]] [[pt:Hidroxila]] [[ru:Гидроксильная группа]] [[fi:Hydroksyyli]] [[sv:Hydroxigrupp]] [[th:ไฮดรอกซิล]] [[vi:Hiđrôxyl]] [[tr:Hidroksil]] [[uk:Гідроксил]] [[zh:羟基]]
