How are cis and trans isomers of stilbene different?
Since the cis and trans isomers of stilbene have different geometries, it follows that upon reaction with bromine they give rise to stereoisomeric bromonium ions and, eventually, products that differ only by their stereochemistry. The product of this reaction, 1,2-dibromo-1,2-diphenylethane, has two stereogenic
What is the stereoselectivity of alkene bromination?
The stereoselectivity of alkene bromination will be examined in this experiment. trans-1, 2-Diphenylethene (common name trans – stilbene) will be brominated to form 1,2-dibromo-1,2-diphenylethane (eq 1). This product exists as three stereoisomers . You will determine which isomer (s) actually form in the reaction.
