Final answer:
The differences in chromatography results between isopropanol and NaCl solution can be explained by the differences in their intermolecular interactions.
Step-by-step explanation:
The differences in the chromatography results between isopropanol and NaCl solution can be explained by the differences in their intermolecular interactions. Isopropanol is a polar molecule which can form hydrogen bonds, while NaCl is an ionic compound that dissociates into ions in solution. The polarity and strong intermolecular forces of isopropanol allow it to interact more effectively with the stationary phase in chromatography, resulting in different separation behavior compared to NaCl solution.
