17.2 REACTIONS INVOLVING ALLYLIC AND BENZYLIC …
www.saplinglearning.com796 CHAPTER 17 • ALLYLIC AND BENZYLIC REACTIVITY when the reaction is promoted by heat, light, or free-radical initiators, an apolar solvent such as CCl 4 is used, and the bromine is added slowly so that its concentration remains very low. To summarize: Addition: (17.14a) Substitution: The effect of bromine concentration results from the rate laws for the competing reactions.
