Selectivity between the sites is often decided by steric effects. Generally electron releasing groups. Examples: -OH, -NH 2, -Me, -F, -Cl, -Br, -I, Meta-directing: Substituents which draw electron density from the ortho and para positions, hence increasing reaction on the meta position. deckhands arcane odysseyWeb1 mrt. 2016 · While later chemists used orth- for 1,2 isomer, meta- for the 1,3 isomer , and pera- for the 1,4 isomer.
