Look on p.388-9. Tertiary C-H bonds are more reactive and require less
energy to break than the bonds of primary C-H bonds. CH<CH2<CH3...

For chlorine, the differences in E_act are small and chlorine can easily
break any of the bonds. For bromine, it is a different story. The
tertiary C-H bond is much, much easier to break than the primary bond.
Thus, the bromine will be more selective towards tertairy C-H bonds!
