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...
