Briefly explain what you would expect the result to be of the following scenario: You have two compounds that you have spotted on the TLC plate. One compound is more polar than the other. You ran the TLC plate with neat hexanes and found that only one spot moved a small distance up the plate. What might you expect to see if you ran a TLC plate in a 50/50 mixture of hexanes and ethyl acetate? What would the spots do?
