1.	The `R_(f)` values of A and B in 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 as a mobile phase, which of the two components, A or B, will elute first? Explain.
Answer» 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.
