BIOCHEMICAL ENGINEERING INSTRUMENTATION - EXAMPLE 29.3 : In thin layer chromatography (TLC), let retention factor Rf = (distance traveled by solute) / (distance traveled by solvent). Silica gel is used as stationary phase which is more polar than the hexane solvent as mobile phase. If the Rf values of 3 solutes A, B and C are 1.5, 0.75 and 1 respectively, compare the polarities of A, B and C with reasons.

BIOCHEMICAL ENGINEERING INSTRUMENTATION - ANSWER 29.3 : Polarities : A < C < B. A is least polar since it travels farthest with the mobile phase, whereas B is most polar as it is attracted to the stationary phase and travels least.
