Provide the correct structure for your unknown based on the spectroscopic data provided. Provide the correct name for your compound. Either the IUPAC name, or a commonly accepted name (i.e., ethyl acetate in place of ethyl ethanoate) will be accepted.IR spectrum: Assign as many peaks as possible. In particular, you should assign peaks that were important in making your structural interpretation (i.e. functional group peaks such as OH, C=O, N-H, etc.). 1H-NMR spectrum: Assign all the peaks in the spectrum...
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...
