WebJan 23, 2024 · The electrophile is CH 3 CH 2+. It is formed by reaction between the ethene and the HCl - exactly as if you were beginning to add the HCl to the ethene. The chloride ion is immediately picked up by the aluminium chloride to form an AlCl 4- ion. That prevents the chloride ion from reacting with the CH 3 CH 2+ ion to form chloroethane. truth honeyWebto dehydrogenation of ethyl benzene to styrene reaction, a set of parallel endothermic reactions can occur that lead to ben-zene and toluene production.
