Question
**Educational Content: Infrared Spectroscopy Analysis** **Objective:** Analyze the given infrared (IR) spectra and match each spectrum to one of the eight chemical compounds listed. **Compounds:** 1. Cyclopentanone 2. 4-Hexen-3-ol 3. 1-Octyne 4. Propanoic acid 5. Cyclohexylamine 6. Benzene 7. Butanoic acid 8. Propanal --- **Infrared Spectra Analysis:** **Spectra Provided:** - The image contains three distinct IR spectra. **Graph Descriptions:** 1. **First Spectrum:** - **X-Axis:** Wavenumber (cm⁻¹) - **Y-Axis:** Transmittance (%) - Notable Peaks: - A broad peak around 3300 cm⁻¹ indicative of an O-H or N-H stretch could suggest alcohol, acid, or amine. - Strong absorption in the region around 1700 cm⁻¹ typically indicates C=O stretching, characteristic of carbonyl groups (such as ketones, aldehydes, or acids). 2. **Second Spectrum:** - **X-Axis:** Wavenumber (cm⁻¹) - **Y-Axis:** Transmittance (%) - Notable Peaks: - Very sharp peak near 2200 cm⁻¹, likely indicating a C≡C or C≡N bond. - Peak around 3300 cm⁻¹ could indicate terminal alkyne C-H stretch. 3. **Third Spectrum:** - **X-Axis:** Wavenumber (cm⁻¹) - **Y-Axis:** Transmittance (%) - Notable Peaks: - Broad peak approximately at 3300 cm⁻¹ suggesting an O-H group like in alcohol or acid. - Strong peak at 1700 cm⁻¹ could indicate C=O stretching typical of carbonyl-containing compounds. - Additional peaks near 2900 cm⁻¹ suggesting C-H stretching. **Analysis Task:** - **Goal:** Match each IR spectrum to one of the eight depicted compounds based on functional group absorptions. - **Procedure:** Examine the peaks in each spectrum and compare them with known absorption values for specific functional groups (e.g., O-H, C=O, C
