Question

The proton NMR spectral information shown in this problem is for a compound with formula $\mathrm{C}_9 \mathrm{H}_{14} \mathrm{O}$. Expansions are shown for all the protons. The normal carbon- 13 spectral results, including DEPT-135 and DEPT-90 results, are tabulated: TABLE CANT COPY Draw the structure of this compound and assign each of the protons in your structure. The coupling constants should help you to do this (see Appendix 5). DIAGRAM CANT COPY

Step 1

This indicates that the compound contains 9 carbon atoms, 14 hydrogen atoms, and 1 oxygen atom. The degree of unsaturation can be calculated using the formula: \[ \text{Degree of Unsaturation} = \frac{(2C + 2 + N - H - X)}{2} \] For this compound, substituting Show more…
