Answer the following questions about radical halogenation
QUESTION 1 Performing allylic bromination of an asymmetric alkene produces two regiochemical outcomes due to resonance, and two conformations (R) and (S) for each chirality center produced. This is further complicated if you make the mistake of using Br2 as your source of bromine radicals, as the addition reaction producing alkyl dibromides competes with the allylic bromination. Br2, hv ??? Categorize each of the compounds shown below as an [A] allylic bromination product,...

What is Wrong?
Select the keyword or phrase that will best complete each sentence. Key terms: A radical is a reactive intermediate with a single unpaired electron, formed by homoloysis of a covalent bond. paired unpaired Allylic radicals are stabilized by resonance, making them more stable than tertiary radicals increases inductive effects A compound that contains an especially weak bond that serves as a source of radicals is called a radical initiator ess homoloysis decreases more J Treatment of cyclohexene...

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...

1. Draw each one of the following molecules and label it as:
alkyl halide, allyl halide or vinyl halide
a) 2-chloro-3-ethylpentane
b) 6-ethyl-3-lodocyclohexene
2. Give all resonance structures of the allylic radical
intermediate that arise from reaction above. All allylic C-H on the
molecule are equivalent so only show the two resonance structures
arising from one C-H bond reacting.
3. Are the resonance structures above equivalent or
non-equivalent?

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...
