In what order would the following compounds be eluted on a silica gel TLC plate if they are spotted on the same plate and developed in a solvent mixture of 10:1 hexanes:ethyl acetate A. 1 has the highest Rf value, then 2 then 4 then 3 b. 4 has the highest Rf value, then 1 then 3 then 2 c. 3 has the highest Rf value, then 2 then 1 then 4 d. 2 has the highest Rf value, then 3 then 1 then 4
Both melting points and TLC rely on differences in non covalent forces. Explain the role of these non-covalent interactions in the final answer obtained (melting point and Rf value).
You will run a TLC plate after the CC placing in one spot the original sample of pigments, one spot from the yellow band and one from the green band. Draw a picture of what you expect to observe after running the TLC plate. Explain.
what is more polar, pyrrole or benzaldehyde? I need to know for a TLC test/ which one should be further up?
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-octene and 1,4-dimethylbenzene gave only one spot with an Rf value of 0.95. The solvent used was acetone.b. A two-component mixture containing a dicarboxylic acid and tricarboxylic acid gave only one spot with an Rf value of 0.05. The solvent used was hexane.c. When a TLC plate was developed, the solvent front ran off the top of the plate.
Which statement about TLC analyses is not true? * A- The line at the base of the TLC plate should be drawn with a pencil. B- To prevent contamination, a new capillary tube should be used to apply each sample. C- Samples should be applied multiple times in the same place to increase the concentrations of any possible compounds in the spot. D- A glass beaker lined with filter paper can be used as a development chamber in a TLC analysis. E- All these statements are correct.
From your results, which component had the highest Rf value and which had the lowest? Based on your answer from the previous question, what could be the reason behind some components having an Rf value higher than the others? Compare the qualities of the two components that rendered the highest and lowest Rf After performing the simulation, what do you think are the possible practical applications of chromatographic techniques that are relevant to your program NURSING?
1. TLC a) What are the results of loading too much compound to a TLC plate?b) What would happen if you added too little compound to a TLC Plate?
Whagt is the purpose of the following? Separate the active ingredients in an unknown over the counter analgesic using TLC (thin layer chromatography). Make a preliminary identification of each active ingredient in an unknown tablet by comparing its Rf value(s) with the Rf values of four different known active ingredients:
if you wanted to makes the spots travel up the TLC plate further, what solvent ration would you choose and why? 1:2 Ethyl acetate/Hexane, 2:3 Ethyl acetate/ Hexane, or 1:1 Ethyl acetate/Hexane
During TLC, what is the stationary phase and what is the mobile phase?
I had having trouble understanding the TLC labs. Could someone help explain how to tell which compound has a higher Rf value? benzoic acid or trans-stilbene?
