ΔH ° rxn for each hydrogen abstraction step depicted in Figure 25-10 is to be calculated using Table25-1. Concept introduction: The rate of halogenation increases with increasing stability of the alkyl radical that is produced on hydrogen abstraction. Thus, not only does radical halogenation tend to be faster at 2° carbons than 1° carbons, but it also tends to be faster at 3° carbons than 2° carbons. Halogenation is particularly favored when hydrogen abstraction produces a resonance-stabilized alkyl radical. Free radical bromination of an alkane is much more selective than free radical chlorination.
