provide structures for the spectral data provided
Pages 1-5: provide the 5 structures for the spectral data provided. For full credit, you must be sure to assign/label all the NMR peaks and assign the major IR bands including those readily identifiable in the fingerprint region (use the IR spectral tables handed out in class). If you do not label anything on the spectra, you will lose most of the points for this problem set. Hint for the problems listed without...
