Electrophilic substitution of benzene

Draw and explain the mechanism of benzene reacting with a charged electrophile E+ such as NO2+: attack by the delocalized pi electrons, the positively charged intermediate and loss of H+ to restore the ring, and explain why benzene substitutes rather than adds.
