Correct answer: A. Seliwanoff Test : This test use to detect the presence of Ketohexose than aldohexose. Reagent : Resorcinol + conc. HCl. Barfoed Test : It if used to detect Monosaccharide by Reduction of Cu(II) into Copper (I). Fehling Solution: It is used to defect aldehyde than Ketone by reduction Cu(II) into Cu(I). Biurate Test : Use to detect presence of peptide bond. Protein by reduction of Cu(II) into Cu(I).
