The major absorption peaks

This combined spectra problem contains some combination of the following information: IR spectrum, NMR (1H-and 13C-) spectrum and mass spectrum with molecular ion peak(s).

1. On each spectrum, analyze and neatly label the major absorption peaks with the structural fragment that causes the absorption.
2. On the answer sheet that follows the spectra, explain all the structural information that can be interpreted from each spectrum.
3. Using your combined analysis of the spectra, propose the molecular formula and the molecular structure of the unknown. Explain how you deduced your unique molecular structure
