Remeber how you learned that a pure liquid distills within anarrow boiling point range, but that narrow boiling point doesntnecessarily imple a pure liquid? Keeping that lesson in mind,explain this: you know without a doubt from spectroscopic techniquethat your product mixture contains 2 distinct products... yet yourTLC plate shows only one spot. How is this possible? The, yourresearch advisor tells you thats its really not that unusual toencounter this kind of conflicting data and that it is often easilyresolved with a little more bench work. What should you do to clearup the issue using the TLC?
