Two compounds I and II are eluted by column chromato-graphy(adsorption of I II). Which one of the following is a correct statement?
Choose an option
Show full solutionCorrect option: B
Correct answer
BII moves faster and has higher value than I
Step-by-step explanation
Since, adsorption of I II, I is firmly attached to column (stationary phase). Hence, it will move slowly and will move little distance. A1so II is loosely attached to column (stationary phase). Hence, it will move faster and will move large distance.
