6. A student performed a TLC experiment with the silica TLC plate by spotting samples of A, B, C, D, E and F on the plate, then eluting with n-hexane/ethyl acetate (8/2). The results of the TLC plate after development are shown on the left. a) Based on this TLC analysis, what are the ingredients of component A? (2 p) b) List the compounds according to their increasing polarity. (2 p) Order the Rf values (except A) of the samples in ascending order. (2p) -------------- A B C D E F d) Comment on how the TLC plate, might look like using n-hexane: ethyl acetate (5:5) as the developing solvent. Explain it briefly. (4 p) e) Write the column leaving order of all these samples. (3 p)
