JEE MAIN - Chemistry (2018 - 15th April Evening Slot - No. 10)
Two compounds I and II are eluted by column chromatography (adsorption of I > II). Which one of following is a correct statement ?
I moves faster and has higher Rf value than II
II movesfaster and has higher Rf value than I
I moves slower and has higher Rf value than II
II moves slower and has higher Rf value than I
Explanation
According to question,
Absorption of I > II, it means I is firmly attached to column. Hence it will move slowly and move little distance. As II is loosely attached to column.
So, it will move faster and will move larger distance.
