The rate-determining step of the bromination of acetone engages breaking a carbon-hydrogen bond. Approximate the ratio of the rate constants Kc-h/Kc-d for the reaction at 300K. 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 as well as c is the velocity of light.
