Essay

Give the structure of a compound with molecular formula C₁₀H₁₂O and that gives the following 1H NMR and ¹³C NMR spectra. Label the hydrogens and the carbons. 1H NMR 1.2 ppm (t, 3H); 2.3 ppm (s, 3H); 2.6 ppm (q, 2H), 7.2 ppm (d, 2H), and 7.8 ppm (d, 2H). ${}^{13} \mathrm{C} \mathrm{NMR}: 7.0 \mathrm{ppm}\left(\mathrm{CH}_{3}\right) ; 20.9 \mathrm{ppm}\left(\mathrm{CH}_{3}\right) ; 32.0 \mathrm{ppm}\left(\mathrm{CH}_{2}\right) ; 128.0(\mathrm{CH}), 129.1 \mathrm{ppm}(\mathrm{CH})$ , $134.0 \mathrm{ppm}(\mathrm{C}) ; 141.0 \mathrm{ppm}(\mathrm{C})$ ; and $198.1 \mathrm{ppm}(\mathrm{C})$ .
