Essay

Give the structure of a compound with molecular formula C₁₀H₁₂O and that gives the following ¹H NMR and ¹³ C NMR spectra. Label the hydrogens and the carbons. 1H NMR spectrum: 1.3 ppm, (d, 6H); 3.1 ppm (sept, 1H); 3.2 ppm (s, 3H); 4.6 ppm (s, 2H), 7.1 ppm (d, 2H), 7.1 ppm (d, 2H) ${}^{13}C NMR$$\text {spectrum:}$ $24.4 \mathrm { ppm } \left( \mathrm { CH } _ { 3 } \right) ; 31.7 \mathrm { ppm } ( \mathrm { CH } ) ; 53.5 \mathrm { ppm } \left( \mathrm { CH } _ { 3 } \right) ; 77.9 \mathrm { ppm } \left( \mathrm { CH } _ { 2 } \right) ; 126.2$ ppm (CH); $127.3 \mathrm { ppm } ( \mathrm { CH } ) ; 134.4 \mathrm { ppm } ( \mathrm { C } )$ ; and $147.8 \mathrm { ppm } ( \mathrm { C } )$ .
