  • Phenol (or hydroxybenzene)
ORGANIC FUNCTIONAL GROUP DERIVED FROM AN AROMATIC RING
Triaryl; Aryl hydrocarbons; Aryl; Aryl groups
In organic chemistry, an aryl is any functional group or substituent derived from an aromatic ring, usually an aromatic hydrocarbon, such as phenyl and naphthyl. "Aryl" is used for the sake of abbreviation or generalization, and "Ar" is used as a placeholder for the aryl group in chemical structure diagrams, analogous to “R” used for any organic substituent.

COMPOUND CONTAINING HALOGEN ATTACHED DIRECTLY TO AN AROMATIC RING
Haloarene; Haloaromatic; Aryl chloride; Halogenoarene; Aryl bromide; Aryl iodide; Aryl halides; Chloroarenes; Halobenzene; Halobenzenes
In organic chemistry, an aryl halide (also known as haloarene) is an aromatic compound in which one or more hydrogen atoms, directly bonded to an aromatic ring are replaced by a halide. The haloarene are different from haloalkanes because they exhibit many differences in methods of preparation and properties.
