The order from top to bottom for naphthalene, butyric acid, and phenylacetate spots developed on silica gel TLC plate should be determined. Concept introduction: TLC works on the principle of separation of constituents of a mixture of compounds based onpolarity. The polar compounds interact with the stationary phase. So, theycan move to smaller distance from the base,whereas, the non-polar compounds tend to move faster as they interact less with the silica gel.Therefore, they move far from the base of the plate.
