Homework Help: chem

Posted by Jason on Tuesday, October 21, 2008 at 12:36pm.

The Rf value of compound A is .34 when the TLC plate is developed in hexane and .44 when the plate is developed in diethyl ether. Compound B has an Rf value of .42 in hexane and .60 in diethyl ether. Which solvent would be better for seperating a mixture of compounds A and B by TLC? Explain.

- I think that the diethyl ether is a better solvent because it is less polar than hexane? Is this the right track?
