If one does tlc , which one would have a higher rf value? trans or cis stillbene, i know the more polar should have the lower rf value, but they are isomers, and the internet gave me 2 opposite answers :/ my thought is that cis stilbene should be less polar because it looks more symmetrical, but can someone confirm? also should it be easy to separate the two since one is a solid and the other is a liquid?
