Assume that the 1H NMR spectrum shown below was obtained on your isolated reaction product. Note that the frequency range of the original spectrum was -0.5 – 12 ppm, but the downfield range (~8.5 – 12 ppm) and upfield (< 4 ppm) were deleted in the printout because no signals were detected on those regions. a) Draw the chemical structure of the B-hydroxyketone intermediate. b) Is there any B-hydroxyketone contained in your reaction product? Why or why not? Refer to...

4. Analyze the IR spectrum of your product, filling in the table below. You should utilize your course textbook (pp. 764-766), if you need assistance. Please note that the frequency given below should be exact (one number), not a range. Use the frequency of the center of the band at its strongest point. Then, on the spectrum itself, mark the characteristic bands at their strongest point with a...
