Practice Problem You are provided with the MS, IR, 'H NMR, and ' C NMR of an unknown compound. Answer the follow questions regarding these spectra and provide the structure of the unknown molecule. 1. What is the molecular formula for the unknown molecule? 2. Calculate the hydrogen deficiency index for the molecule? What information can you obtain from the mass spectrum of the compound. Give m/z and assignment of a structure. (show a minimum of three) What information can you obtain from the IR spectrum? Give frequency and peak assignment. 5. Analyze the 'H NMR spectrum. For each group of signals in the spectrum, report the thultiplet siructure in 6. List the 13C chemical shifts for your molecule. Write the 8 values on your structure. (It might be helpful to have two separate structures, one for 1H NMR and one for 13C NMR) Propose a structure for the unknown molecule.
