WebThe above said positions (ortho and para) are the most reactive towards an electron-poor electrophile, thus promoting electrophillic substitution reaction. The methyl group hence makes it around 25 times more reactive than benzene hence making its nitration more easier than that of benzene. WebThe mechanism of electrophilic aromatic nitration was revisited. Based on the available experimental data and new high-level quantum chemical calculations, a modification of the previous reaction mechanism is proposed involving three separate intermediates on the potential energy diagram of the reaction.

Benzene is a planar molecule having delocalized electrons above and below the plane of the ring. Hence, it is electron-rich. As a result, it is highly attractive to electron-deficient species i.e., electrophiles.Therefore, it undergoes electrophilic substitution reactions very easily.
