Consider, for example, the TLC plate pictured at right after developing and UV visualization where prior to elution, lanes A and B were spotted with 4-t-butylphenol and lanes B and C spotted with benzamide. Which of the following must be true? In the space provided, indicate the CORRECT answers (as 1, 2, and/or 3) then explain your reasoning for all three statements. Benzamide elutes faster than t-butylphenol. The Rf for t-butylphenol is less than that of benzamide. Benzamide is more polar than 4-t-butylphenol

Question
Despite their structural differences, separation of mixtures of organic compounds (such as the arenes benzoic acid, 4-t-butylphenol, and benzamide) often proves difficult. Silica gel chromatography, however, can be used with some success provided that an appropriate solvent is used to provide optimal separation.
