Question: Explain the mechanism of nitration of benzene?

Nitration is a reaction where nitrogen is added to a molecule. Nitration of benzene occurs through the use of nitric acid. This reaction is catalyzed by concentrated sulfuric acid. The sulfuric acid acts as a dehydrating agent to help remove water from the reaction. Nitration of benzene occurs in two steps. First, the nitronium ion, NO2+, is formed. This is an electrophilic species and it attacks the benzene ring by displacing one of the hydrogen atoms from the benzene ring. This forms an intermediately, nitrobenzene. Finally, a proton, or hydrogen, is abstracted from the nitro group to return the reaction back to a benzene ring with a nitro group attached.
