In chemistry , the chlorine anisoles form a group of substances that are derived from both anisole and chlorobenzene . The structure consists of a benzene ring with attached methoxy group  (–OCH 3 ) and chlorine  (–Cl) as substituents . Their different arrangement ( ortho , meta or para ) results in three constitutional isomers with the empirical formula C 7 H 7 ClO.
