WebThe spots that were developed in 100% ethyl acetate, are located higher up the TLC for both benzophenone and biphenyl. The results for 100% hexanes, were located at much lower regions for both benzophenone than biphenyl. Therefore, we can conclude that 100% hexanes is the most polar solvent, which explains the low Rf values obtained.
