- The compounds biphenyl and naphthalene are presented in a mixture. Can hexane be used as a solvent to separate the compounds by column chromatography with silica gel as the stationary phase? Why or why not.Compound A has a lower affinity for the stationary phase thancompound B and can dissolve well in the mobile phase. In theseparation of the mixture of A and B by column chromatography,which compound will be eluted first from the column? ExplainWhat is the other term for mobile phase in chromatography? (Eluant, Eluate, or Solvent)
- Is it easy to difficult to separate p-anisic acid and vanillin by column chromatography? (using ethanol as solvent) If yes, is it because of the structure of both molecule where they are soluble in ethanol?List the expected order of the compounds in Caraway oil to leave the chromatography column. Explain the order based on the functional groups contained in the molecules.What would be the order of elution if one separated the three compounds from base/base extraction (3-nitrotoluic acid, 2-naphthol and 1,4-dimethoxybenzene) on column chromatography using silica as stationary phase and ethyl acetate/hexanes as mobile phase. Explain
- Gestation time arrangement of Hegran, Hexanol, and Benzene compounds in the reverse phase of column liquid chromatography.Is it easy to separate benzoic acid and naphthalene by column chromatography? (using ethanol as solvent) If yes, is it because of the structure of both molecule where benzoic acid is soluble in ethanol (hence can remain in aqueous solution) and naphthalene is insoluble in the ethanol so can remain as organic layer?Of Aspirin, ethanol, acetaminophen, ethyl acetate, hexane, and water which could go undetected during HPLC analysis, but could result in a lower than expected melting point, why are they not detected by HPLC analysis?
