WebbScore: 4.8/5 (50 votes) . 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. WebbL. S. Romsted, J. Zhang and L.
