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:...

1. What is the expected product melting point if the bromination of stilbene by PHPB is completely stereospecific (anti addition)? 2. How would the melting point be affected if the reaction is not completely stereospecific and the dibromide product contains significant amounts of dl-stilbene dibromide, as well as the expected meso stilbene dibromide? Note the widely differing melting points of the meso and dl isomers. 3. What is the theoretical yield of dibromide product in the bromination reaction? 4. How...
