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? 4. Give all the products expected from the reaction above....
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,...
