Explain the regiochemical outcome for chlorination of bromobenzene. Ortho attack and para attack are preferred because each of these pathways involves a sigma complex withresonance structures. Attack at the meta position involves formation of a sigma complex with only resonance structures. The reaction will proceed more rapidly via the energy sigma complex, so attack takes place at the ortho and para positions in preference to the meta position.
