* Stationary Phase Attraction: A component that's minimally attracted to the filter paper will spend less time bound to the paper and more time moving with the solvent.
* Solvent Solubility: High solubility in the solvent means the component readily dissolves and moves along with the solvent flow.
In Summary: These components will be located near the solvent front, which is the furthest point the solvent reaches on the filter paper.
