In discussing radical halogenation, the following image was presented: Hydrogen abstraction (in the chlorination process) Hydrogen abstraction (in the bromination process) 1° radical Alkane + 1° radical 2º radical Potential energy Potential energy 2° radical 3° radical 3° radical Alkane + Reaction coordinate Reaction coordinate The difference in energies of the primary, secondary and tertiary radicals are the same whether it's chlorination or bromination. Why are the activation energies to each type of radical so different when comparing chlorination to bromination (the green box area).
