Is it possible to use Thin Layer Chromatography (TLC) to analyze a distillation sample. For instance, if I completed a Simple Distillation and wanted to find the identity of the distillate, would it be possible to do this through TLC? Please explain fully why or why not.
Homework Answers
No,since after simple distillation we can separate volatile liquid from nonvolatile liquid i.e. on the basus of difference of boiling point .But TLC is generally used separate mixture of liquid on the basis of adsorption.so distillate can be identified in the way like liquid has low boiling point or more volatile vapourised first and then high boiling liquid which take time to vapourise can be collected by condensing vapour of it after sometime.

1.a IR spectroscopy and Thin Layer Chromatography (TLC) is very convenient in tracking reactions. Explain How you used both IR and TLC to track your reaction. Was your reaction complete when you did your initial TLC check? If so, how can you tell? 1.b Discuss how yield can be correlated to the efficacy of a reaction? Why are yields never 100%?

11. Why should you use pencil instead of pen when marking on a thin layer chromatography plate? a. Pencil lead isn't as dark. b. The components of pen ink will separate along with your sample, while pencil lead will not. c. Pen ink will not mark on a TLC plate. d. Pen ink will undergo a chemical reaction with the solvent. 12. Which of the following is not a reason to use thin-layer chromatography? a. To determine the number of...

Wanting to monitor the reaction progress you decide to use normal phase thin-layer chromatography, but do not know what the best conditions are to use. If you had the standards for all potential products and your starting materials, outline how would you go about determining the best TLC conditions for monitoring the reaction progress. Provide drawings of an ideal TLC plate with the number of theoretical products you would expect and their relative positions. How do you know when the...

In our Thin-Layer Chromatography Lab, we were asked to determine the components of Excedrin by analyzing the development of aspirin, acetaminophen, and caffeine on a TLC plate and compare it to Excedrin's development. Pure ethyl acetate was used as the solvent, and each analyte was mixed with 95% ethanol. Unfortunately, our professor suspected that our TLC plates were old/deteriorated as every group was unable to detect CAFFEINE or ASPIRIN with a UV lamp, but ACETAMINOPHEN and EXCEDRIN were easily detected...
