Saha, J. … WebGomberg–Hey, 40 °C1.14: 1.83: 1.00: 1.18 ... For chlorination reactions, the relative rate of hydrogen atom abstraction is 1 for primary, 3.9 for secondary, and only 5.2 for tertiary, which means that a tertiary hydrogen atom is removed only 5.2 times faster than a primary, so there is much less selectivity. Halogen radicals will abstract ...
