7. An unknown compound has the following IR, 1H-NMR, and 13C-NMR spectra. In a mag spectrum of this compound, the (M)* peak appears at m/2 = 104 and the (M+1)* peak 4.4% the height of the parent ion peak. Elemental analysis shows that the compound onl consists of C, H, and O. Please determine the molecular formula of the molecule am deduce the structure of the molecule (20 points): % Transmittance 1742 4000 3500 3000 2500 2000 150010 Wavenumber (cm) Proton NMR Expansion Vanishes â in D,0 FTMS - in D,0 Dom 3 2 1 0 Chemical Shift (ppm) Carbon NMR DEPT-135 160 120 80 Solvent- Proton decoupled 160 200 120 80 Chemical Shift (ppm) 80****
