The `R_f` value of A and Bin a mixture determined by TLC in a solvent mixture are 0.65 and 0.42 respectively. If the mixture is separated by column chromatography using the same solvent mixture on a mobile phase, which of the two components A or B will elute first?

Text Solution

Verified by Experts

Since the `R_(f)` value of A is 0.65, therefore, it is less strongly adsorbed as compared to component B with `R_(f)` value of 0.42. Therefore, on extraction of the column, A will elute first.
