Concept introduction:
An electrophilic aromatic substitution reaction is a type of reaction in which an electrophile substitutes a hydrogen atom of the aromatic ring. Aromatic ring does not easily undergo nucleophilic substitution reaction; however, it undergoes electrophilic substitution reaction easily.
