A) II moves slower and has higher \[{{R}_{f}}\]value than I
B) II moves faster and has higher \[{{R}_{f}}\] value than I
C) I moves faster and has higher \[{{R}_{f}}\] value than II
D) I moves slower and has higher \[{{R}_{f}}\] value than II
Correct Answer: B
Solution :
Two compounds I and II are eluted by column chromatography (adsorption of I > II). The statement (B) is a correct statement. II moves faster and has higher \[{{R}_{f}}\] value than I Since, adsorption of I > II, I is firmly attached to column (stationary phase). Hence, it will move slowly and will move little distance. Also, II is loosely attached to column (stationary phase). Hence, it will move faster and will move large distance.
