Both the regioselectivity—the diverse arene substitution patterns—and the speed of an electrophilic aromatic substitution are affected by the substituents already attached to the benzene ring. In terms of regioselectivity, some groups promote substitution at the ortho or para positions, whereas other groups favor substitution at the meta position. These groups are called either ortho–para directing or m… WebDec 29, 2014 · EAS reactions are classified as activating when describing the effect on the EAS reaction of occurring multiple times on the same ring.
