**Exercise 5: Analysis of Thin-Layer Chromatography (TLC) Development in Varying Solvent Ratios**The given exercise requires imagining the effects of different solvent ratios on the positioning of the spots on a TLC plate.**Problem Statement:**The following TLC plate was originally developed using a 4:1 hexane/acetone solvent mixture.**Tasks:**a) Predict and draw the appearance of the TLC plate if developed with a 9:1 hexane/acetone ratio.b) Predict and draw the appearance of the TLC plate if developed with a 1:1 hexane/acetone ratio.**Illustrations:**1. **TLC Plate with 4:1 Hexane/Acetone Ratio:** - This plate shows two distinct spots located in the middle section of the plate. The solvent front is indicated by a dashed line near the top, and the baseline is indicated by a dashed line at the bottom.2. **TLC Plate with 9:1 Hexane/Acetone Ratio:** - An empty rectangle is shown, representing a blank canvas to predict the movement of spots when a less polar solvent system is used.3. **TLC Plate with 1:1 Hexane/Acetone Ratio:** - Another empty rectangle represents a blank canvas for predicting the movement of spots with a more polar solvent system.**Explanation:**- **Increasing the Hexane Ratio (9:1):** Likely results in less movement of polar compounds (dots less spread) as hexane is non-polar. - **Increasing the Acetone Ratio (1:1):** Likely allows polar compounds to travel further up the plate (dots more spread) due to increased polarity of the solvent mixture.This exercise explores how changing the polarity of the solvent mixture affects the migration of substances on a TLC plate, essential for effective separation in chromatography analysis.
