An aryl halide is a compound formed by the substitution of a halogen atom for a hydrogen atom on benzene. Another name for an aryl halide is halobenzene.
Aryl halides are named by prefixing the name of the halogen to benzene. For example:
Properties of aryl halides
The physical properties of unsubstituted aryl halides are much like those of the corresponding alkyl halides. Thus, boiling points, melting points, and solubilities of aryl halides are very similar to those of alkyl halides containing the same number of carbon atoms.
