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

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...
