(N/A) Electrophilic $(E)$ substitution $(S)$ reactions of benzene are known as aromatic $S_E$ reactions.
Aromatic $S_E$ reactions occur in three steps:
$(i)$ Generation of the electrophile: The electrophile $(E^+)$ is generated from the reagent.
$(ii)$ Formation of the carbocation intermediate ($\sigma$-complex): The electrophile attacks the benzene ring to form a resonance-stabilized carbocation intermediate. This is the slow,rate-determining step.
$(iii)$ Removal of the proton: $A$ base removes a proton from the $sp^3$ hybridized carbon of the $\sigma$-complex to restore the aromaticity of the benzene ring. This step is fast.
