Thin layer chromatography of a mixture shows the following observation: The correct order of elution in the silica gel column chromatography is

Step-by-step solution

The process of extraction of different compounds absorbed on the column by means of a suitable solvent (eluent) is called 'elution'. Silica gel and solvent methylene chloride both are polar. The polar solvent and silica gel bind the polar compound, so it moves very slowly, whereas the non-polar compound moves faster on the silica gel. Correct order of elution →   A   >   C   >   B
