WebNitration and sulfonation of benzene are two examples of electrophilic aromatic substitution. The nitronium ion (NO 2+) and sulfur trioxide (SO 3) are the electrophiles and individually react with benzene to give nitrobenzene and benzenesulfonic acid respectively. Nitration of Benzene WebNitration of benzene is the name for such a process. The mechanism of benzene nitration is as follows: Step 1: Nitric acid absorbs a proton from sulphuric acid before dissociating to generate the nitronium ion. Step 2: In the reaction, the nitronium ion functions like an electrophile, reacting with benzene to generate an arenium ion. Step 3 ...
