determine the structure of your unknown from the molecular formula, IR, and 13C NMR spectra. assign all of your 13C NMR absorptions. IR & 1C NMR Lab Unknown Your group's mission is to determine the structure of your unknown from the molecular forrmula, IR and 13C NMR spectra. Assign all of your C NMR absorptions. You want to know which resonances correspond to which parts of the product's structure. The best way to do this is to draw a picture...
Must know the unknowns name and structure. NAME IR & 13C NMR Unknown Your mission is to determine the structure of your unknown from the molecular formula, IR and 'SC NMR spectra. Assign all of your 3C NMR absorptions. You want to know which resonances correspond to which parts of the product's structure. The best way to do this is to draw a picture of the molecule right on the NMR spectrum then label each C on the molecule with...
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...
Provide the correct structure for your unknown based on the spectroscopic data provided. Provide the correct name for your compound. Either the IUPAC name, or a commonly accepted name (i.e., ethyl acetate in place of ethyl ethanoate) will be accepted.IR spectrum: Assign as many peaks as possible. In particular, you should assign peaks that were important in making your structural interpretation (i.e. functional group peaks such as OH, C=O, N-H, etc.). 1H-NMR spectrum: Assign all the peaks in the spectrum...
please help me answer the IR, H NMR and 13C NMR questions based on the pictures below. IR List the important peaks seen in the IR of the product and label with the associated stretches and bends (eg. C-H stretch, etc). 13C NMR List all the peaks in the 13C NMR and give them each a number. Write the structure of the product and label the carbons with the associated number for the peak. (The peaks from 21-25 can be...

10. Briefly explain how the 13C-NMR data was used to determine (or confirm your proposed structure. 11. In both of the boxes below, draw the bond-line structure with appropriate bond angles) of your unknown. On the structure on the left, indicate with a label (peak #from table above) and arrow the source of each signal. On the structure of the right, indicate with a label (13C-NMR ppm) and arrow the source of each signal. Chapter 5: INTEGRATED SPECTROSCOPY PROBLEMS 139...
