Chemistry:Alkoxy group
In chemistry, the alkoxy group is an alkyl group which is singularly bonded to oxygen; thus R–O. Denoted usually with apostrophe('). The range of alkoxy groups is vast, the simplest being methoxy (CH
3O–).[1] An ethoxy group (CH
3CH
2O–) is found in the organic compound ethyl phenyl ether (C
6H
5OCH
2CH
3, also known as ethoxybenzene).
Related to alkoxy groups are aryloxy groups, which have an aryl group singularly bonded to oxygen such as the phenoxy group (C
6H
5O–).
An alkoxy or aryloxy group bonded to an alkyl or aryl (R–O–R') is an ether. If bonded to H it is an alcohol.
The term alkoxide refers to the anionic conjugate bases of alcohols (RO−
) or to ionic compounds containing such an anion. Alkoxide compounds are derivatives of alcohols where the hydrogen of the –OH group is replaced by a metal;[2] for example, the sodium salt of ethanol (CH
3CH
2OH) is sodium ethoxide, containing ethoxide anions CH
3CH
2O−
and sodium cations Na+
.
