Column Chromatography works by the same principle as TLC however the silica gel is not plated on a plate but it is packed into a glass (or plastic column) and the eluting solvents runs down a column by gravitational pull. The mixture from question 1 (above) is analyzed by column chromatography using the same mobile phase and a silica gel stationary phase. Which component has the shorter retention time? Explain your answer. (Assume the same type of binding forces between the components and the stationary phase are present in both paper chromatography and column chromatography.)
