WebThe reaction to form the bromotoluene isomers is fast and irreversible and does not attain equilibrium. The methyl group attached to the benzene ring is an activating group, that is, it makes the aromatic ring more reactive than benzene itself. Bromotoluene is a group of three isomeric chemical compounds. They (ortho-bromotoluene, meta-bromotoluene, and para-bromotoluene) consist of a disubstituted benzene ring with one bromine atom and one methyl group.

If a substituted benzene undergoes further substitution mostly at the ortho and para positions, the original substituent is called an ortho, para-directing group. Thus, bromine is an ortho, para-directing group, because all electrophilic substitution reactions of bromoben-zene occur at the ortho and para positions.
