3. You ran column chromatography and collected a fraction each minute for 25 minutes, then you analyzed them all by TLC. The resulting TLC data is below. Please note that in this example ferrocene has the highest Rr, acetyl ferrocene the second highest Rr, and diacetyl ferrocene has the lowest Rr. 4 11 12 13 14 15 Minutes e 16 17 18 19 20 Assuming your goal was to collect pure acetyl ferrocene, which fractions should you combine and recrystallize to collect only that compound? Explain clearly. 4. Could you use infrared spectroscopy to distinguish between ferrocene and acetylferrocene? In your answer, discuss any relevant functional groups and how the presence or absence of specific peaks would assist you in answering this question. For any specific peaks mentioned, give the frequency range where you might expect to find them. 3.
