pectra C and D: These are the full spectra for the aldol addition and aldol condensation products respectively. Analyze each spectrum to see if you can detect any unreacted 2-acetylpyridine or p-nitrobenzaldehyde. First choose one signal in each starting material as the diagnostic signal for your assessment. Then in each spectrum, point to where these diagnostic signals ARE or WOULD BE if
they were present. What is your conclusion?
