6. Which of the pigments migrated the farthest and why the separation of pigments occur as it did?

The pigment that typically migrates the farthest in chromatography is usually carotene, due to its non-polar nature, allowing it to dissolve more readily in the non-polar solvent used in the process. The separation of pigments occurs because of differences in their solubility and affinity for the stationary phase (usually paper or silica). More polar pigments, like chlorophyll, interact more strongly with the stationary phase and thus migrate more slowly. This differential migration results in the distinct separation of pigments along the chromatographic medium.
