Identify the compound with molecular formula $\mathrm{C}_{8} \mathrm{H}_{10} \mathrm{O}$ that gives the IR and $^{1} \mathrm{H}$ NMR spectra shown here.
Deduce the structure of the compound that gives the following $\left.^{1} \mathrm{H},^{13} \mathrm{C}, \text { and } \mathrm{IR} \text { spectra (Figs. } 9.40-9.42\right) .$ Assign all aspects of the $$^{1} \mathrm{H}, \text { and }^{13} \mathrm{C}$$ spectra to the structure you propose. Use letters to correlate protons with signals in the $$^{1} \mathrm{H} \mathrm{NMR}$$ spectrum, and numbers to correlate carbons with signals in the $$^{13} \mathrm{C}$$ spectrum. The mass spectrum of this compound shows the molecular ion at $m / z 96$ (FIGURE CANNOT COPY)
