4. An unknown aromatic compound (C₂H₁₁NO₂) displays the following ¹H and ¹³C APT NMR spectra. Determine the structure and draw this compound to the right of each spectrum. Label the unique sets of protons and carbons on the corresponding structures and then use those numbers to label the NMR signals. Hint: The 2 broad singlets in the ¹H NMR make up the NH₂ of an amide group. 9 HSP-43-829 d 13C APT NMR bs 8 td lbs 7 6 5 ppm q 4 3 2 t 1 0
