WebbNitro (NO 2 ), sulfonic acid (SO 3 H) and carbonyl (C=O) substituents have a full or partial positive charge on the atom bonded to the aromatic ring. Structures in which like-charges are close to each other are destabilized by charge repulsion, so these substituents inhibit ortho and para substitution more than meta substitution. Webb20 aug. 2024 · With the nitronium ion electrophile formed, it can react with the benzene ring. The π electrons of the benzene ring (which are drawn as double bonds) nucleophilically attack the electrophilic nitrogen of the nitronium ion, cleaving one of the N=O π bonds, with the electrons going onto the oxygen (giving it a negative charge):

WebbBenzene is nitrated using the nitronium ion, NO2+, which acts as our electrophile. It is generated by mixing concentrated sulfuric and nitric acids (H2SO4 and HNO3). Sulfuric acid is a stronger acid than nitric acid, so nitric acid is forced to act as a base - it accepts a proton given up by sulfuric acid.
