Electrophilic substitution reaction

--Mechanism Of Aromatic Electrophilic Substitution Reactions-- The Aromatic Ring has a planar structure with a closed conjugation.It has pi-electrons which are mobile. 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,
