The substitution reaction of toluene with Br2 can, in principle, lead to the formation
Chapter 15, Problem 15.50(choose chapter or problem)
The substitution reaction of toluene with Br2 can, in principle, lead to the formation of three isomeric bromotoluene products. In practice, however, only o- and p-bromotoluene are formed in substantial amounts. The meta isomer is not formed. Draw the structures of the three possible carbocation intermediates ( 15.49), and explain why ortho and para products predominate over meta.
