Question

# The electrophilic aromatic substitution proceeds through a: A. Free radicalB. sigma complexC. BenzyneD. Carbene

Hint: Electrophilic aromatic substitution reaction is those in which the electrophile is responsible for the replacement of the atom from the aromatic ring. During the reaction, the formation of the sigma bond takes place.

-In this type of reaction, firstly the electrophile which has a positive charge attack on the $\pi$-bond of the aromatic ring forms carbocation.
