Unknown C304
2. Identify the important (diagnostic) peaks from the IR spectrum. List the cm−1 and the bond that corresponds to each peak below. Be sure to also add labels your IR spectrum (write the corresponding bond type next to each peak on the IR spectrum itself). 3. List the functional group(s) or class(es) of compound that your unknown could be (i.e. could the unknown be a ketone, alcohol, ester, carboxylic acid? does the compound contain C=C double or triple bonds? does it contain a benzene ring? etc). 4. From the mass spectrum, identify the m/z value for the parent ion and base peak(s). Be sure to label these on your MS.

5. Uxinginformation from the IR and MS, determine the molecular formula and calculate the degree of anaturation. Be sure to showe your work 6. How many unique types of carbons are present in the molecule? 7. For each unique carbon, list the chemical shitt and possible hybridiration. 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.
