In the resonance hybrid of the arenium ion (sigma complex) formed during the electrophilic attack on — Aromatic Hydrocarbons Chemistry Question

💡 Solution & Explanation

The electrophile forms a covalent bond with one carbon atom, which becomes $sp^3$ hybridized and electrically neutral. The remaining 5 carbon atoms in the ring remain $sp^2$ hybridized, and the positive charge is delocalized across them via resonance.
