Basic purpose of this article is to Discuss on Synthesis of Aryl Halides. An aryl halide is a compound formed by the substitution of an halogen atom for any hydrogen atom on benzene. Another name on an aryl halide ishalobenzene. The physical properties of unsubstituted aryl halides are similar to those of the equivalent alkyl halides. Thus, boiling points, melting points, and solubilities of aryl halides are akin to those of alkyl halides containing a similar number of carbon atoms.
