This is an illustration of TLC plates. The compounds used were syn-azobenzene (A) and anti-azobenzene (B). The difference between the two plates are that the first was placed in 15% methylene chloride in pet. ether and the second was placed in 30% methylene chloride in pet. ether. I calculated Rf values to be 0.47 mm for syn-azobenzene and 0.44 mm for anti-azobenzene in 15% while syn-azobenze had a Rf of 0.28 mm and 0.16 mm. Which solvent is best at separating and how does Rf help identify which isomer is which? I read that the anti is supposed to have a higher Rf but that is not the case here so I want to know if the syn is supposed to have the higher Rf and the anti is supposed to have the lower one.
