(Consider the following silica gel TLC plate of compounds A, B, and C developed in hexanes 04 ABC -solvent from ongis (ii) (a) Determine the Rf values of compounds A, B, and C. (The distance between the origin and the solvent front is 4 cm. Spot A moved 1.5 cm, Spot B moved 3.5 cm, Spot C moved 3 cm). (ii) (b) Which compound is the most polar? (iii) What would you expect to happen to the Rf values if you used ethyl acetate instead of hexanes as the eluting solvent?
