Chlorobenzenes are a group of aryl chlorides/halobenzenes consisting of one or more chlorine atoms as substituents on a benzene core. They have the formula C₆H_6–nCl_n, where n = 1–6 is the number of chlorine atoms. Depending on the number of chlorine substituents, there may be several constitutional isomers possible.
