**NMR and IR Spectroscopy Analysis** **Objective:** To determine the structure of the given compound using IR and \( ^1H \) NMR spectroscopy data. **Molecular Formula:** \( C_6H_{12}O_2 \) **IR Data:** - Absorption Peak: 1743 cm\(^{-1}\) This indicates the presence of a carbonyl (C=O) functional group, likely from an ester or ketone. **\( ^1H \) NMR Spectrum Analysis:** - The horizontal axis represents the chemical shift in ppm (δ), ranging from 0 to 8 ppm. - The vertical axis shows the signal intensity. 1. **Signal at δ = 4.1 ppm (2H, Triplet, J = 6.7 Hz):** - Indicates a triplet, suggesting the presence of a CH2 group adjacent to another CH2 group. - Analyzed as an ethoxy group. 2. **Signal at δ = 2.3 ppm (2H, Quartet, J = 7.6 Hz):** - Indicates a quartet, corresponding to a CH2 group adjacent to a -CH3 group. 3. **Signal at δ = 1.6 ppm (2H, Multiplet):** - Shows a multiplet, likely indicating the presence of another CH2 group adjacent to a complex environment. 4. **Signal at δ = 1.25 ppm (6H, Doublet, J = 7.4 Hz):** - Displays a singlet, suggesting a CH3 group not adjacent to any protons that would couple with it. 5. **Signal at δ = 0.9 ppm (3H, Triplet, J = 7.6 Hz):** - Indicates a triplet, consistent with a CH3 group next to a CH2 group. **Conclusion:** Combining the information from the IR and \( ^1H \) NMR spectra, we can infer the presence of functional groups and the connectivity within the molecule. The signals confirm the presence of a methylene group, a methoxy group, and other alkyl chains. **Next Step:** **Draw the compound.** The IR indicates an ester functional group, and the NMR data provide insights into the alkyl chain environment around these groups. --- This transcription aims to guide students through interpreting NMR and IR
