Alkoxy group
Template:Short description Template:Refimprove
In chemistry, the alkoxy group is an alkyl group which is singularly bonded to oxygen; thus Template:Chem2. Denoted usually with apostrophe('). The range of alkoxy groups is vast, the simplest being methoxy (Template:Chem2).<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}Template:Deadlink</ref> An ethoxy group (Template:Chem2) is found in the organic compound ethyl phenyl ether (Template:Chem2, 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 (Template:Chem2).
An alkoxy or aryloxy group bonded to an alkyl or aryl (Template:Chem2) is an ether. If bonded to H it is an alcohol.
The term alkoxide refers to the anionic conjugate bases of alcohols (Template:Chem2) 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;<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> for example, the sodium salt of ethanol (Template:Chem2) is sodium ethoxide, containing ethoxide anions Template:Chem2 and sodium cations Template:Chem2.
