How can you distinguish cis and trans stilbene?

WitrynaBromination of cis-stilbene Note: Slightly less cis-stilbene is used in this experiment than trans-stilbene due to the relative cost of the two isomers. The difference in cost reflects the relative difficulty of synthesizing each isomer. Since the trans isomer is the more stable, it is easier to make and costs less.
