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 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...

which of these statements below are true of thin layer chromatography? a. the mode of separation is generally by absorption or partition b. the more polar components are adsorbed preferentially by the polar layer c. hydrogen bonding is the main force controlling adsorption between the silica gel surface and the analyte functional groups d. silica gel with or without an added fluorescing indicator is most commonly used stationary phase in normal phase chromatography e. all of the above

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...
