$(2)$ The intermediate carbocation in this reaction is highly resonance stabilized. Not

counting the carbocation above, draw three additional resonance forms of this

carbocation, illustrating how the positive charge can be delocalized onto one of the

aromatic rings on three different carbons.

Step $1$: Formation of carbocation $($rate limiting$)$

Step $2$: Nucleophilic attack on the carbocation

$($fast$)$

Final Step: Loss of proton to solvent
