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).

Biaryls may display [[axial chirality]].
