MCAT Question of the Day


  • Q:

    Thin layer chromatography (TLC) involves the separation of compounds based on differences in polarity. The compounds interact differently with the solvent and the solid matrix, resulting in a different rate of travel along the solvent front as it wicks along the surface of the solid matrix. Consider a TLC experiment using a solid matrix of silica with diethyl ether as the solvent. Three compounds are dissolved in the ether: tyrosine (structure shown below), benzaldehyde, and phenol (hydroxybenzene). In which order will the compounds follow the solvent front?



     

    A

    phenol, benzaldehyde, tyrosine

    B

    phenol, tyrosine, benzaldehyde

    C

    benzaldehyde, tyrosine, phenol

    D

    benzaldehyde, phenol, tyrosine
