How many major Kekule-style resonance structures can be drawn to represent the delocalization of the positive charge in the arenium ion formed during the electrophilic attack on unsubstituted benzene?

Question

Prashant Kotian · Accepted Answer

Correct answer: B. Once the sp3 carbon forms, the remaining 5 sp2 carbons share the positive charge. The charge rotates strictly between the ortho and para positions relative to the sp3 carbon, generating exactly 3 resonance structures.
