Question

The rate of o-nitration of the compounds (I) toluene, (II) 2-D-toluene and (III) 2,6-D₂-toluene is in the following order : (I) (II) (III)

TestHub · Accepted Answer

In the rate-determining step of nitration the electrophile adds to the ring; C-D bond cleavage is not involved. So there is no isotope effect and I = II = III.
