Step 1: Recall the  Formula

Step 2: Read TLC Data from the Figure

- Solvent front distance: 12.5 cm from baseline
- Sample A spot: 5.0 cm from baseline
- Sample C spot: 10.0 cm from baseline

Step 3: Calculate Individual  Values

Step 4: Calculate the Ratio and Convert

Converting to the required format :

Therefore .

Key Points to Remember:
- Sample C (higher ) → less polar → would elute first from a column
- Sample A (lower ) → more polar → would elute last from a column
- In TLC,
