Electrophilic substitution

This reaction involves the conversion of [benzene or arene , electrophile] to [aryl compound].

The specific reaction demonstrated here is of the conversion of [benzene & cyclohexene] to [1,4-Dicyclohexylbenzene] using catalyst [\ce{ H2SO4 (protonator) }].

It is significant in that [it shows how protonation can provide otherwise hard to obtain compounds.]
