Toluene is a methyl derivative of benzene. All carbon atoms of benzene are sp 2 hybridized while the carbon atom of methyl group is sp 3 hybridized bonded with three hydrogen atoms and one aromatic carbon atom.he methyl group on benzene ring in toluene is ortho and para directing and activating group due to hypercojugation and positive inductive effect of methyl group. Out of ortho and para products, ortho products are formed as major products around 63%, with para 34% and 3% meta products.
