5. For the following sets of spectra do the following: 1. Determine a reasonable formula and calculate degrees of unsaturation. 2. Use the IR spectrum to predict which functional groups exist. 3. Use the chemical shifts and coupling of the 1HNMR spectrum to determine the number and types of protons present. Integration values are below each peak. 4. Determine a reasonable structure, label the protons, and match the protons to the peaks of the 1HNMR spectrum. Verify that the chemical shift, integration, and coupling values make sense
