A general mechanism for aromatic electrophilic substitution reaction is. (K_(1) and K_(2) are rate constant for the forward reaction) also C-D bond in harder to break than a C-H bond, and consequently reaction in which C-D bond broken proceed more slowly than the reaction in which C-H bond are broken. However experimetns reveal that nitration of C_(6)H_(6) and C_(6)D_(6) proceeds at equal rates while the same is not true for sulphonation of C_(6)H_(6) and C_(6)D_(6). Q. When one of the carbons of benzene is labelled (C^(14)), in which case we expect greater yield of the product obtained at labelled carbon.
