SOLVED: Draw a TLC plate using ChemDraw chromatography for trans-cinnamic acid (Rf value: 0.27), menthol (Rf value: 0.64), and isovanillin (Rf value: 0.2) using a 75:25 ratio of hexanes to ethyl acetate. Please label the spots, solvent front, mobile phase, and Rf value. What information can you obtain from this analysis?

which of the following compounds would have the lowest rf value on a tlc plate 77797

which of the following compounds would have the lowest rf value on a tlc plate 77797

1. Suppose a TLC plate shows only one spot at an Rf value of0.99. Does this mean the sample is pure? Explain2. In general what happens to Rf value in TLC when the polarityof the developing solvent is decreased?

SOLVED: The following is the schematic drawing of the TLC result from Part B of Experiment 5. (a) Determine Rf values for all the spots on the TLC. Show your work. (b) Identify the unknown. (c) Explain how the structural features of each compound affect its relative mobility on the TLC. (d) When John finished Part B of Experiment 5, he dried the plate carefully and returned it to the developing chamber. What would you expect the Rf value of acetaminophen to be relative to the origin after the se
