The rate determining step of the bromination of acetone involves breaking a carbon hydrogen bond. Approximate the ratio of the rate constants Kc-h/Kc-d for the reaction at 300K. Explain the frequencies of vibration for the particular bonds are Vc-h 30001/cm Vc-d 2100 1/cm. The wave number is given by v/c where v is the frequency and c is the velocity of light.
