For the fleshy covering of certain seeds, see [[aril]].'' In the context of organic molecules, '''aryl''' refers to any [[functional group]] or [[substituent]] derived from a [[simple aromatic ring]], may it be [[phenyl]], [[thiophene|thiophenyl]], [[indole|indolyl]], etc (see [[IUPAC nomenclature]]). "Aryl" is used for the sake of abbreviation or generalization. A simple aryl group is [[phenyl]], C<sub>6</sub>H<sub>5</sub>; it is derived from [[benzene]]. The tolyl group, CH<sub>3</sub>C<sub>6</sub>H<sub>4</sub>, is derived from [[toluene]] (methylbenzene). The [[xylyl]] group, (CH<sub>3</sub>)<sub>2</sub>C<sub>6</sub>H<sub>3</sub>, is derived from [[xylene]] (dimethylbenzene). [[Image:Aryl groups.PNG|thumb|center|500 px|A few different types of benzene derived aryl groups. From left to right: [[phenyl]], [[benzyl]], tolyl, o-[[xylyl]].]] Biaryls may display [[axial chirality]]. ==See also== *[[Alkyl]] *[[Aromatic hydrocarbon]] *[[Aromaticity]] *[[Heterocycle]] [[Category:Functional groups]] {{organic-compound-stub}} [[de:Arylgruppe]] [[es:Grupo arilo]] [[fr:Aryle]] [[it:Arile]] [[mk:Арил]] [[nl:Aryl]] [[ja:アリール基]] [[pl:Grupa arylowa]] [[pt:Arila]] [[ru:Арил]] [[sv:Arylgrupp]] [[zh:芳基]]
