**Question 2: TLC Plate Analysis****Problem:** What potential problem can a student encounter when an \( R_f = 0 \) is obtained for an unknown sample on a silica TLC plate developed with a hexane mixture?**Solution:** The issue here is that the compound did not move from the origin, indicating it is too polar to be eluted by the non-polar hexane solvent. To resolve this, consider using a more polar solvent or solvent mixture to increase compound movement during the TLC experiment.

THIN LAYER CHROMATOGRAPHY (TLC) is used for identification of unknown compounds, here compound move…
