A reverse phase TLC plate because the polar stationary phase will interact with polar compounds more strongly.

A normal phase TLC plate because the nonpolar stationary phase will interact with nonpolar compounds more strongly.

Answer:A normal phase TLC plate because the polar stationary phase will interact with polar compounds more strongly.

Explanation:TLC(THIN LAYER CHROMATOGRAPHY) is a solid (stationary phase) and a liquid(mobile phase) technique of separation and purity determination that uses the principle of that different compounds have different adsorption rate and different solubility rate to the two phases between which they are partitioned.

ON A DEVELOPED THIN LAYER CHROMATOGRAPHIC PLATE A PURE COMPOUND WILL APPEAR ONLY ON ONE SPOT.

With TLC one can analyse multiple samples at the same time.
