Vedclass · Answer

(B) In column chromatography,the compound that is more strongly adsorbed on the stationary phase moves slower through the column. Given that the adsorption of $I > II$,compound $I$ is more strongly adsorbed than compound $II$. Therefore,compound $I$ moves slower and travels a shorter distance,while compound $II$ moves faster and travels a longer distance. The $R_f$ value is defined as the ratio of the distance traveled by the substance to the distance traveled by the solvent front. Since compound $II$ travels a greater distance,it has a higher $R_f$ value than compound $I$.

Two compounds $I$ and $II$ are eluted by column chromatography (adsorption of $I > II$). Which one of the following is a correct statement?
