(b) (d) The following page contains spectra for Unknown X. Identify Unknown X based on these spectra. Draw your answer in the box provided below. Use this page to explain your logic (including how you determined the molecular formula). On both NMR spectra, assign as many peaks as you can by numbering the peaks from left to right, redrawing Unknown X in the box provided, and labeling each carbon or hydrogen atom with the appropriate peak number. For atoms that cannot be assigned with certainty, list the signals to which they might reasonably correspond. Label any important peaks on the Mass Spectrum (with formulas of the fragments).
