Question

The proton NMR spectral information shown in this problem is for a compound with formula $\mathrm{C}_{12} \mathrm{H}_8 \mathrm{~N}_2 \mathrm{O}_4$. An expansion is shown for the region between 8.3 and $7.2 \mathrm{ppm}$. No other peaks appear in the spectrum. Analyze this region to determine the structure of this compound. Strong bands appear at 1352 and $1522 \mathrm{~cm}^{-1}$ in the infrared spectrum. Draw the structure of this compound. DIAGRAM CANT COPY
