Relative boiling points of the components

Relative molecular weights of the components

Relative attraction of components to the stationary and mobile phases (correct)

Relative concentration of components in the mixture

Column chromatography uses a flat surface and capillary action, while planar chromatography involves a narrow column and gravity or pressure for mobile phase flow

Column chromatography uses a gas mobile phase, while planar chromatography uses a liquid mobile phase

Column chromatography involves a narrow column and gravity or pressure for mobile phase flow, while planar chromatography uses a flat surface and capillary action for mobile phase movement (correct)
