An unequal stereoisomeric product mixture results from the reaction of trans-stilbene with pyridinium tribromide. What is the major product of this reaction and should there be any optical activity in a solution containing the product mixture?
If cis-stilbene were used as our starting material in place of trans-stilbene, what change in product mixture content and optical activity would you expect?
