An efficient laboratory experiment has been developed for undergraduate students to conduct hydrogen-deuterium (H-D) exchange of resorcinol by electrophilic aromatic substitution using D2O and a catalytic amount of H2SO4. The resulting labeled product is characterized by (1)H NMR. Students also visualize a significant kinetic isotope effect (kH/kD ≈ 3 to 4)(More)
