Can you help me figure out which graphs make what compound please? Based on IR?

### Infrared Spectroscopy Analysis This educational module presents infrared (IR) spectra for three compounds, illustrating the characteristic absorption peaks and functional groups. #### Top Spectrum: n-Hexane - **Graph Explanation:** - **Wavenumber Range:** 4000 to 600 cm⁻¹ - **Characteristic Peaks:** - 3000 cm⁻¹: C–H stretch - 1460 cm⁻¹: C–H bending - **Identification:** - The spectrum labeled "(a) n-hexane" highlights peaks at typical alkane C–H stretching and bending regions. #### Middle Spectrum: 1-Hexene - **Graph Explanation:** - **Wavenumber Range:** 4000 to 600 cm⁻¹ - **Characteristic Peaks:** - 3080 cm⁻¹: =C–H stretch from the alkene group - 1642 cm⁻¹: C=C stretch - 1460 cm⁻¹: C–H bending - **Identification:** - Labeled "(b) 1-hexene," this spectrum includes alkene-specific absorption bands, differentiating it from n-hexane by the presence of the C=C stretch. #### Bottom Spectrum: 1-Hexyne - **Graph Explanation:** - **Wavenumber Range:** 4000 to 600 cm⁻¹ - **Characteristic Peaks:** - 3324 cm⁻¹: ≡C–H stretch (terminal alkyne) - 2126 cm⁻¹: C≡C stretch - 1383 cm⁻¹: C–H methyl rock - 1470 cm⁻¹: C–H scissoring - 636 cm⁻¹: C≡C–H bending - **Molecular Structure:** Includes a diagram of 1-hexyne with the molecular formula C₆H₁₀. - **Identification:** - The spectrum for "1-hexyne" shows distinct bands for the alkyne group, particularly at the ≡C–H and C≡C stretch regions. #### Summary These spectra provide visual cues for identifying functional groups in organic compounds through characteristic IR absorption peaks. Each spectrum represents a different type of

The image contains six infrared (IR) spectra corresponding to different organic compounds. These spectra are presented alongside structural formulas of the compounds. Each graph displays transmittance (%) on the y-axis and wavenumber (cm<sup>-1</sup>) on the x-axis, highlighting characteristic peaks associated with specific functional groups. **Spectra Details:** 1. **Top Left Spectrum:** - Displays peaks corresponding to an alcohol. - Major peaks include O-H stretch around 3350 cm<sup>-1</sup>, sp<sup>3</sup> C-H stretches at 2950 cm<sup>-1</sup>, and C=O stretches between 1800 and 1700 cm<sup>-1</sup>. 2. **Top Right Spectrum:** - Correlates with a carboxylic acid. - Shows prominent peaks at 2500-3300 cm<sup>-1</sup> for O-H stretch, approximately 1710 cm<sup>-1</sup> for C=O stretch, and C-O stretches around 1250 cm<sup>-1</sup>. 3. **Middle Left Spectrum:** - Features an ester. - Notable peaks at 1750 cm<sup>-1</sup> for C=O stretch, and C-O stretch around 1200 cm<sup>-1</sup>. 4. **Middle Right Spectrum:** - Represents an amine. - Displays peaks at 3400 cm<sup>-1</sup> for N-H stretch, and around 1580 cm<sup>-1</sup> for C=C stretch. 5. **Bottom Left Spectrum:** - Corresponds to an alkyne. - Shows a significant peak at 3300 cm<sup>-1</sup> for C≡C-H stretch, and at 2100 cm<sup>-1</sup> for C≡C stretch. 6. **Bottom Right Spectrum:** - Relates to a ketone. - Features peaks around 1700 cm<sup>-1</sup> for C=O stretch and weaker C-H stretching peaks around 3000 cm<sup>-1</sup>. Each spectrum provides insights into the functional groups present in the compound, aiding in the structural identification of organic molecules.
