Aromatic compounds undergo eiectrophilic substitution reaction. Those groups which increase the electron density on ortho, para position (v i z,- CH 3,- C 2 H 5.,- OH, - Br, - NH 2, - NH R etc.) are called ortho/para directing group substituents, which increases electron density on meta position (- NO 2,- CN ,- CHO ,- COR.- COOH ,- COO R,- SO 3 H etc.) are meta directing groups.
