Consider a sample that is a mixture composed of biphenyl, benzoic acid, and benzyl alcohol. The sample is spotted on a TLC plate and developed in a CH2C12-cyclohexane solvent mixture. Predict the relative Rf values for the three components in the sample. Would biphenyl be closest to the blotted line, then benzyl alcohol, then benzoic acid because these others are increasing in polarity to the non-polar solvent? Thanks!
