Ortho- and para-directing groups

CHO, -COOH, -CONH, -CN, -NO, -SO3H, and the chief ortho and para directing groups are ... [Pg.159]

The curved arrows show how one resonance structure relates to another. Notice that the formal negative charge is located on the ortho and para positions, exactly where reaction takes place most quickly. Other ortho- and para-directing groups include —NH2, —Cl, and —Br. All have an atom with a lone pair of electrons next to the ring, and all accelerate reaction. [Pg.863]

Explain why ortho- and para-directing groups accelerate electrophilic substitution on the benzene ring and identify such groups (Section 18.8). [Pg.866]
