So I completing a lab report and one of the sections is on TLC analysis. In the experiment, the TLC plate was submerged in toluene ethylacetate and had spots of cinnamon leaf oil, cinnamon aldehyde, and cinnamon bark oil. 9 spots total were seen under the UV light, but different spots appeared following a vanillin stain. Why is this so and what does this mean?
In an experiment of Reverse Phase chromatography using C-18 stationary phase and a mixture of methanol/ethyl acetate/acetic acid, a researcher tried to separate the 3 compounds shown below. Which compound would have the lowest Rf and which the highest Rf in this experiment? Explain your answer and show any relevant structures.
b. Answer the questions about the compounds below. جو عید بھید A OH B i) Which compound would have the highest Rf value by TLC? ii) Which compound would have the lowest Rf value by TLC? iii) Which compound would elute first in column chromatography? iv) Which compound would elute last in column chromatography?
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
In a gas chromatogram, the retention time of compounds A and B are 1.25 min and 1.45 min, respectively. If both of these compounds have similar structures, which of the compounds has a higher boiling point?
The fourth paragraph of your conclusions section should describe how thin layer chromatography could be used to monitor a reaction. Specifically, describe how you could use thin layer chromatography to determine when the reaction “oxidation of methoxybenzaldehyde to methoxybenzylalcohol" has gone to completion. Explain whether the reactant or product would have a larger Rr value, and how you could use that fact with a TLC experiment to know when the reaction is complete. The equation for the reaction is:
The following chromatographic peaks indicate the undesirable interaction and separation that taken place. Explain in detail how these undesirable interaction and separation happen for each chromatographic peak. b с d a
