bined Spectra Problems All Together": within mbined Spectra Problems friends, the moment has come... pre puring the past two semesters, we have talked about infrared spectros- (IR), 'H-NMR spectroscopy, "C-NMR spectroscopy, and Mass spec trometry (MS). We've also talked about using information gathered from the mass spectrum to generate a molecular formula and the index of hydro- gen deficiency which helps us determine information about our compound when there isn't any available.

1151 VCL 11-8: Claisen Condensation -1 For this assignment, the target compound that you should synthesize is methyl acetoacetate. This is another carbonyl addition variation. Examine the product and determine which ester is the nucleophile and which is the electrophile. Keep in mind the mechanism and that you need to acidify the intermediate in order to isolate a neutral product. Synthesis Procedures 1. Start Virtual ChemLab and select Claisen Condensation-I from the list of assignments in the electronic workbook. After...

Experimental Data Only report the IR absorptions that provide diagnosis for the major functional groups. Copies of your spectra will be included in your lab report with this information written on the spectra. However, the information should also be included in the body of the report in a text format similar to the example given below IR cm1: 1735 (C-o); MS:...

PART 3 For each set of data on pages 5-9, calculate and record the degree of unsaturation. Then use your problem solving skills to determine the chemical structure that is consistent with ALL of the data on each page. You are not required to label the spectra (but feel free to do so). This entire assignment is to be completed independently Suggestion for a general method to determine a chemical structure based on the provided molecular formula, IR, H-NMR and...
