Question
Chapter 6.2, Problem 3E
Interpretation Introduction
Interpretation:In a TLC experiment, the reason for the spot of the sample to be analyzed to not immersed in the solvent in the developing chamber should be explained.
Concept introduction:Thin Layer Chromatography is a sensitive chromatographic technique which used to analyze small quantities of the samples by solid-liquid adsorption method. Rectangular glass plate is coated with anadsorbent; sample to be analyzed is run on the plate in the developing chamber with the mobile phase to give spots of the analyzed sample.

How does increasing the polarity of the developing solvent affect the Rf of a compound on a silica gel TLC plate?
What would happen if we use longer columns and select adsorbing materials with 200-400 mesh sizes for gel filtration chromatography using a column experiment?
Why is it necessary to run TLC in a closed container and to have the interior vapor saturated with the solvent? What error is introduced into the determination of an Rf value if the top is left off of the developing chamber?
