III IV 5. The product of free-radical halogenation reactions is an alkyl halide. The major amount of this halide forms during the second step of propagation. However, you should be aware that one possible termination step also forms alkyl halides. Why does the majority of the alkyl halide product come from the propagation step and not the termination step? A. At any given time during the reaction, the concentration of both the alkyl radical and the halide...

188 ChemActivity 20 Radical Halogenation of Aanes Model 8: Selectivity of the Photo-Halogenation Reaction • Radical halogenation with F, is unselective, violent and dangerous limiting the usefulness of this reaction in organic synthesis. • Radical halogenation with le is so slow as to be useless in organic synthesis • Radical halogenation with Br, is right It is very useful in organic synthesis. The rate is manageable and reactions with Br, are very...

Model 8: Selectivity of the Photo-Halogenation Reaction Radical halogenation with Fis i olent and dangerous limiting the usefulness of this reaction in organic synthesis Radical halogenation with lis so slow as to be useless in organic synthesis Radical halogenation with Br, is just right! It is very useful in organic synthesis. The rate is manageable and reactions with Bry are very selective. (A selective reaction gives close to 100% of a single product. An unselective reaction gives...
