Which of the following is a correct statement regarding electrophilic aromatic substitution? A. Many suitable electrophiles are unreactive and can be stored for long periods of time prior to use. B. The carbocation intermediate will lose a proton to regain aromaticity, usually from a position other than the site of the electrophilic attack. C. Formation of the carbocation intermediate has a high activation barrier due to loss of aromaticity. D. Reformation of the aromatic ring has a low activation barrier and therefore occurs slowly. E. The carbocation intermediate has several resonance structures and is negatively charged.
