The 1H NMR for 2,3-dibromobutane has a doublet at 1.8 ppm and a quartet at 4.5 ppm. Draw the compound and assign the peaks in the spectrum to their respective protons.
for the following 2 compounds, please calculate, and
show the calculations for, the degree of unsaturation, assign the
IR spectrum peaks, assign the 13C NMR peaks, assign the 1H NMR
peaks, and draw the structure for the unknown compound.
CHIM 245 Spectroscopy Problem Set #2 In this problem set there are two unknown compounds. You are provided with the formula, IR spectrum, "C NMR spectrum, and 'H NMR spectrum for each compound. Each unknown is worth 10 points, with an...
Draw a H NMR spectrum for each compound. Pay attention to the chemical shift (ppm) multiplicity, and integration of each peak. The boxes indicate where the peaks should go (which ppm range) as well as the relative height of each peak OH PPM O 3 PPM -2. H 10 8 PPM
4. Draw a clear and accurate NMR spectrum for the molecule shown below. Clearly show the number of peaks, and the integration, chemical shift and splitting of each peak. PP 5. Use the chemspider.com to look up the NMR spectrum for the compound in 4. Compare that spectrum to your answer in 4. Draw that spectrum here, explaining the differences between the actual spectrum and what you predicted. Don't worry if you what you initially drew was incorect PPM
