How many major Kekule-style resonance structures can be drawn to represent the delocalization of the β Aromatic Hydrocarbons Chemistry Question
Question
How many major Kekule-style resonance structures can be drawn to represent the delocalization of the positive charge in the arenium ion formed during an electrophilic attack on benzene?
Answer: B
π‘ Solution & Explanation
Once the $sp^3$ carbon forms, the remaining 5 $sp^2$ carbons share the positive charge. The charge is delocalized over the ortho and para positions relative to the $sp^3$ carbon, generating exactly 3 distinct resonance structures.
