5. Using information from the IR and MS, determine the molecular formula and calculate the degree of unsaturation. Be sure to show your work. Molecular Formula: CiUHIZO Degree of unsaturation: 5 √ 11 =10+1 = 1/2 (12-0) 1/2 (12) 6. How many unique types of carbons are present in the molecule? 7. For each unique carbon, list the chemical shift and possible hybridization. 8. On the basis of your analysis above, propose a structure that fits all the data. Be sure the structure you propose fits your IR, MS and "C NMR data. 9. Propose the structure of the fragment that corresponds to the base peak. 10+1 = 6 11=6 10. Attach labeled copies of your spectra to this sheet. 124 Carbon-13 Nuclear Magnetic Resonance ("C NMR) Spectroscopy Laboratory 10
