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. In the space below. draw a 'H NMR spectrum for each of the following molecules. Note that only one of these will be graded but you must complete BOTH in order to receive any credit. Assign ALL signals in your spectrum to the structure, (5 pts.) OCH PEM PPM
1. In the H NMR, draw the structure of the molecule directly on the spectrum and identify each unique proton. Indicate which proton is responsible for each peak. 2. In the IR spectrum, indicate which functional group is responsible for each important peak. Attempt to identify at least five important peaks. In you discussion, indicate which peaks are most helpful in determining whether or not you converted the starting material to the desired product. 3. Compare the IR spectrum of...
