Question

The proton NMR spectral information shown in this problem is for a compound with formula $\mathrm{C}_{10} \mathrm{H}_9 \mathrm{~N}$. Expansions are shown for the region from 8.7 to $7.0 \mathrm{ppm}$. 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
