$K_{C_6H_6} > K_{C_6D_6} > K_{C_6T_6}$

Vedclass · Answer

(A) The sulphonation of benzene is a reversible reaction where the rate-determining step involves the cleavage of the $C-H$ (or $C-D$ or $C-T$) bond.Due to the primary kinetic isotope effect,the $C-H$ bond is easier to break than the $C-D$ bond,which in turn is easier to break than the $C-T$ bond.Since the $C-H$ bond is the weakest and the $C-T$ bond is the strongest,the rate of reaction follows the order: $K_{C_6H_6} > K_{C_6D_6} > K_{C_6T_6}$.
