The Rf value of a compound A is 0.34 when developing a TLC plate in pentane and 0.44 in diethyl ether. Compound B has an Rf Value of 0.42 in pentane and 0.60 in diethyl ether. Select which solvent would be better for seperating the 2 compounds and why

34 and 0.42 respectively. The difference in Rf values is 0.42 - 0.34 = 0.08. Show more…

The Rf value of a compound A is 0.45 when a TLC plate is developed in diethyl ether and 0.34 when the plate is developed in hexane. Compound B has an Rf value 0f 0.43 in hexane and 0.60 in diethyl ether. Which solvent would be better for separating a mixture of A and B by TLC? Explain your answer.

(@) Calculate the Rf values for compounds X, Y, and Z on the following TLC plates: Which development solvent do you think gave the best results, briefly explain? 50% Ethyl Acetate/50% Hexane 10% Ethyl Acetate/90% Hexane A mixture of X, Y, and Z from the previous problem was to be separated using column chromatography. The TLC results are a good predictor of how the column will work. If the mixture is eluted with 100% ethyl acetate in hexane, which compound would be expected to come off the column first, which one will be last? Hexane
