  3. View the solution and report whether you got it right or wrong.
Below are the experimental 1H and 13C NMR spectra of an unknown organic compound, and the MS and IR data is given. What is the structure of the compound? Label relevant spectral data in each spectra you can use to base your assignment on (each spectra must be labelled). The molecular ion is not observed in the MS spectra, so what are the peaks?

MS peaks [molecular ion not observed]: 43 (100), 71 (29); IR peaks: 2974 cm-1 and 1716 cm-1
