is a structure with the carbocation closer to the aromatic ring more stable?

Yes, a structure with the carbocation closer to the aromatic ring is generally considered to be more stable because the positive charge of the carbocation can be delocalized or stabilized by the pi-electron system of the aromatic ring through resonance. This delocalization of the positive charge helps to distribute the charge and stabilize the carbocation, making it more stable compared to a carbocation further away from the aromatic ring.
