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,...

Bromination of trans-Stilbene Introduction can drastically valla very viss The alkene halogenation reaction is a class of reacties in which ha s as clectrophiles 10 attack double bond. Reactivity of halogens can drastically in the fileness of a halogenation react For example, the high reactivity of fluorine e of jodine results in very slow orine pas causes a very vigorous reaction while the low reactivity reactions. Chlorine and bromine showmoderate reactivity and a commonly used in this type of reaction:...
