Electrophilic aromatic substitution Guide, Meaning , Facts, Information and Description
An electrophilic aromatic substitution is a chemical reaction in which a hydrogen atom of an aromatic ring is replaced by an electrophile. When the electrophile approaches the aromatic ring, the electrons are displaced. The structure gets charged due to electromeric/mesomeric effect. This leads to the formation of a pi-complex. Formation of a complex is followed by the formation of Sigma Complex. The Sigma Complex is stable due to resonance taking place.The Attacking Groups can be classified as:
- Activating Groups
Five membered heterocyclic compounds
These compounds undergo aromatic electrophilic substitution reactions under much milder conditions.This is an Article on Electrophilic aromatic substitution. Page Contains Information, Facts Details or Explanation Guide About Electrophilic aromatic substitution
