The proton NMR spectral information shown in this problem is for a compound with formula $\mathrm{C}_{10} \mathrm{H}_{12} \mathrm{O}_3$. A broad peak appearing at $12.5 \mathrm{ppm}$ is not shown in the proton NMR reproduced here. The normal carbon-13 spectral results, including DEPT-135 and DEPT-90 results, are tabulated:
$$
\begin{array}{cll}
\hline \text { Normal Carbon } & \text { DEPT-135 } & \text { DEPT-90 } \\
\hline 15 \mathrm{ppm} & \text { Positive } & \text { No peak } \\
40 & \text { Negative } & \text { No peak } \\
63 & \text { Negative } & \text { No peak } \\
115 & \text { Positive } & \text { Positive } \\
125 & \text { No peak } & \text { No peak } \\
130 & \text { Positive } & \text { Positive } \\
158 & \text { No peak } & \text { No peak } \\
179 & \text { No peak } & \text { No peak }
