WebbWhen all this is true you can think about adding the (NO2) OR (C2H3O) after you have added Br to your benzene. Your last reaction has to be a nitration because an acyl can not be added when there is a moderately strong de activator a.k.a. the (NO2) with the partial positive moment. Someone correct me if I'm wrong. :) 1. bromination 2. acetylation Webb7.5.2 The electrophilic mechanism of nitration of arenes like benzene and methylbenzene. The nitrating mixture consists of concentrated nitric acid (source of the nitro group -NO 2) and concentrated sulphuric acid which acts as a catalyst and as a strong acid.. The overall nitration reaction is the substitution of -H in the benzene ring by the nitro group -NO 2

"WebbAlso, as noted earlier, toluene undergoes nitration about 25 times faster than benzene, but chlorination of toluene is over 500 times faster than that of benzene. From this we may conclude that the nitration reagent is more reactive and less selective than the halogenation reagents. Both sulfonation and nitration yield water as a by-product.
