Aryl
From Free net encyclopedia
In the context of organic molecules, aryl refers to any functional group or substituent derived from a simple aromatic ring. There are more specific terms, such as phenyl, to describe unsubstituted aryl groups and subsets of aryl groups (as well as arbitrarily substituted groups: see IUPAC nomenclature), but "aryl" is used for the sake of abbreviation or generalization.
Biaryls may display axial chirality.
