For each structure 1 through 3 drawn below predict the number of resonance peaks that would be found in the 13C NMR spectrum of the compound. Then indicate all groups of carbons within each molecule that have a homotopic, enantiotopic, or diastereotopic relationship. An unknown compound was found to have the molecular formula C9H11NO. Calculate the index of unsaturation for this compound. What does this result suggest about the compound? The IR and 13C NMR spectra for this compound are shown on the next page. Use the data to determine a structure consistent with the spectroscopy and formula data. Analyze each spectrum as completely as possible by assigning all 13C NMR resona
