When a stuent ran a silica TLC of acetylsalicytic acud using 1:1 mixture of hexane and ethyl acetate, the spot remained on the baseline.

A. What is the Rf value of the spot?

B. Suggest a solvent or mixed solvent ratio that would give a higher Rf value of acetylsalicylic acid on silica TLC. Justify your answer.

Which TLC solvent system would lead to a higher Rf value when analyzing banana oil, 4:1 hexane/ethyl acetate or 2:1 hexane/ethyl acetate? Please explain your answer thoroughly.

Consider the following errors that could be made when running tlc. Indicate what should be done to correct the error.

A. A two component mixture containing 1-octane and 1,4-dimethylbenzene have only one spot with an rf value of 0.95. The solvent was acetone.

B. A two-component mixture containing a dicarboxylic acid and a tricarboxylic acid gave only one spot with an rf value of 0.05. The solvent was hexane

C. When a tlc plate was developed, the solvent ran off the top of the plate.

An unknown mixture was analyzed using TLC on a silica gel plate and developed in 1:6 ethyl acetate:hexane, and gave 2 spots with Rf values of 0.6 and 0.5 respectively. 1)Would this be considered a good separation between the two? Briefly explain. 2)Which spot represents the more polar compound(s)? 3)Can you say for sure how many compounds are contained in the mixture? If so, how many are there? Briefly explain. 4)If not, what further conditions might be performed to determine the number of components in the mixture or to obtain a better separation? Explain. 5)Suppose you carry out a TLC separation of acetaminophen and aspirin on silica gel using a nonpolar eluting solvent, hexane. Which should have the larger Rf value? Briefly explain. 6)What are the methods for "visualizing" spots on TLC plates that we will use in this lab?
