7. An unknown compound has the following IR, H-NMR, and 13C-NMR spectra. In a mass spectrum of this compound, the (M)+ peak appears at m/z = 104 and the (M+1)+ peak is 4.4% the height of the parent ion peak. Elemental analysis shows that the compound only consists of C, H, and O. Please determine the molecular formula of the molecule and deduce the structure of the molecule 3420 1742 4000 3500 30002500 2000 500 Wavenumber (cm) Proton NMR Vanishes in DO TMS 4.4 4.0 3.6 ppm1.4 1.2 10 9 Chemical Shift (ppm)
