Reaction of nitrobenzene with fe/hcl

WebThe mechanism for nitration of benzene: Step 1: Nitric acid accepts a proton from sulphuric acid and then dissociates to form nitronium ion. Step 2: The nitronium ion acts as an electrophile in the process which further reacts with benzene to form an arenium ion. Step 3: The arenium ion then loses its proton to Lewis base forming nitrobenzene.
