Step 1
The IR spectrum shows several key features: - A broad absorption around 3300 cm⁻¹ indicates the presence of an O-H group (alcohol). - Peaks around 2900-3000 cm⁻¹ correspond to C-H stretching (aliphatic). - A strong absorption around 1700 cm⁻¹ suggests a C=O group Show more…

Deduce the structure of the compound that gives the following $$\left.^{1} \mathrm{H},^{13} \mathrm{C}, \text { and } \mathrm{IR} \text { spectra (Figs. } 9.46-9.48\right)$$ 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 ular ion at $m / z 204$ (FIGURE CANNOT COPY)
Compound X has a molecular formula C10H12O and has the IR and 1H NMR spectra shown below. Relative integrations are given below each NMR signal. Figure 1. IR spectrum of compound C10H12O Figure 2. 1H NMR spectrum of compound C10H12O with zoom-in spectrum of aromatic region Draw the molecular structure of compound X in the box, and use letters (A, B, C, etc.) to assign the hydrogens on the molecule to their corresponding signals in the 1H NMR spectrum:
