Aldol Data Report Instruction Chem 420 S2021 (26pts) Introduction (6pts) 1. Explain, with a reaction, why a Lewis acid is necessary in this aldol reaction. 2. Write the reaction scheme for your aldol experiment. Experimental Results: (20pts) 3. IR peak assignments: Identify four significant peaks and assigned them to functional groups. (4pts) 4. NMR peak assignments (8pts) assign all peaks to the correct protons; (assignment of different aromatic peaks is not expected, only which are aromatic; include integrations. The CHCl3 peak at 7.24ppm in the CDCl3 solvent is expected and is not considered a contaminant. Identify major contaminants in your spectrum. Contaminant may be learned by reviewing the experimental procedure. If no contaminant, then say “no contaminants.” (An expansion of signal(s) from diastereotopic protons will be used in the Aldol Analysis Report.) 5. Discussion of product purity by NMR.(6pts) 6. Attach all raw spectra (IR and NMR spectra).(2pts) The report does not have to follow the JOC formatting guideline. Include the following sections as described above,: Introduction Experimental Resulta Attached Spectra
