Abstract

Abstract The abstraction of hydrogen and deuterium atoms from CH 2DCH 2Cl by ground state chlorine atoms generated photochemically from chlorine has been studied at temperatures between 9 and 95°C. The relative rates for the internal competition are found to conform to an Arrhenius rate law: The moderately strong “rprimary” kinetic isotope effect k 2/ k 3 decreases with increasing temperature from 5.51 at 280 K to 4.08 at 365 K. Neither the magnitude of the primary kinetic isotope effect nor the activation energy compares favourably with the values obtained using the bond energy-bond order method. The occurrence of a weak α secondary kinetic isotope effect,
