7) Alkenes can be selectively brominated in the allylic positions with NBS in CCl4. The reaction is selective for substitution at the allylic positions and the allylic bromide product usually is the one with the most substituted and/or stable alkene bond. For example, allylic bromination of 1-hexene produces only trans-1-bromo-2-hexene. (8 points) a. Write the reaction for the light initiated bromination of cyclohexene with NBS in CCIA. b. Write the mechanism using fishhook arrows to show bond making and...

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,...
