In chemistry, chlorobenzenesulfonic acids form a group of substances that are derived from both benzene sulfonic acid and chlorobenzene . The structure consists of a benzene ring with an attached sulfonic acid group (–SO 2 OH) and chlorine (–Cl) as substituents . Their different arrangements ( ortho , meta or para ) result in three constitutional isomers with the empirical formula C 6 H 5 ClSO 3 .
