Propose a detailed mechanism for the allylic bromination of the following.
Explantion: In a radical allylic bromination of alkenes with NBS reaction, why does allylic bromination occur instead of alkene bromination? Secondly, why does the more substituted alkene predominate if more than one alkene can form from such a reaction?

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,...
