Two Important Reaction Patterns: Ortho- , Para- Directors and Meta- Directors It’s one thing to learn about electrophilic aromatic substitution reactions of benzene itself. But
Read moreUnderstanding Ortho, Para, and Meta Directors
Ortho-, Para– and Meta– Directors In Electrophilic Aromatic Substitution (EAS), some substituents on benzene will direct the electrophile E to the ortho– (1,2)and para– (1,4) positions. These
Read moreWhy are halogens ortho- para- directors?
Why are halogens ortho-, para- directors? All activating groups are also ortho-, para- directors. Halogens (F, Cl, Br, I) are notable in that they are deactivating ortho-, para- directors.
