Question
The image displays an infrared (IR) spectrum for a sample labeled as "Unknown C NEAT." The graph is plotted with the wavenumber (in cm⁻¹) on the x-axis, ranging from 4000 to 450 cm⁻¹, and the percentage transmittance (%T) on the y-axis, ranging from 40% to 102%. ### Key Features of the IR Spectrum: 1. **Broad Peaks:** - **2958.34 cm⁻¹ and 2873.37 cm⁻¹:** Characteristic peaks that may suggest C-H stretching vibrations commonly seen in alkanes. 2. **Moderate Peaks:** - **1737.03 cm⁻¹:** Could indicate the presence of a C=O stretching vibration, typical of carbonyl groups such as ketones or esters. - **1467.20 cm⁻¹ and 1436.10 cm⁻¹:** Often associated with CH₂ and CH₃ bending vibrations. 3. **Smaller Peaks:** - **1368.56 cm⁻¹, 1256.26 cm⁻¹:** Could be indicative of C-H bending or C-O stretching. - **1194.38 cm⁻¹:** Often related to ether C-O stretching or ester groups. 4. **Fingerprint Region:** - **1100.65 cm⁻¹, 1011.55 cm⁻¹, 881.86 cm⁻¹, 830.91 cm⁻¹, 711.28 cm⁻¹, 592.08 cm⁻¹:** This region is complex and often used to identify specific functional groups or structural features within the molecule. ### Conclusion: This spectrum provides comprehensive information about the functional groups present in the unknown compound. By analyzing the peak positions and intensities, specific functional groups can be deduced, aiding in the identification of the chemical structure.
