If you were to repeat this experiment using mixtures of hexane and acetone (in the same proportions) as eluent (i.e. replaced the ethyl acetate with acetone) what effect would you predict this change would have on the Rf values for the analgesics?

If this experiment were repeated using hexane and acetone in the same proportions as the one were used with ethyl acetate and hexane the effect of the Rf value would be less because acetone is more polar than ethyl acetate and since the value of the Rf depends on the polarity of the compounds the traveling distance of the spotted acetone will not travel as high as the one in ethyl acetate in in TLC plate.
