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...

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%?

Why is thin layer chromatography used to determine the purity of a sample when you could use an IR spectrum? How does TLC confirm the purity?

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...

Which of the following statements regarding thin layer chromatography are TRUE? Partition chromatography separates compounds based on how they distribute themselves between the stationary and mobile phases. In thin layer chromatography, a polar organic compound will be attracted to the adsorbent and therefore travel further up the plate than a non-polar compound The Rf value is independent of the adsorbent material used. In thin layer chromatography, a polar organic compound will be repelled by the adsorbent and therefore travel not...
