Lower numbers on this axis correspond to longer wavelengths.- **Y-Axis (%T):** Indicates the percentage of transmittance, ranging from 0% to 77%. Higher transmittance means less absorption of IR radiation at that particular wavenumber.### Key Peaks and Their Positions:1. **3306.43 cm⁻¹:** This peak generally indicates N-H or O-H stretching, common in alcohols, amines, or phenols.2. **2925.44 cm⁻¹ and 2855.79 cm⁻¹:** These peaks are indicative of C-H stretching vibrations, typically found in alkanes or aliphatic compounds.3. **1483.71 cm⁻¹:** This peak may correspond to C-H bending, often seen in alkanes.4. **1374.44 cm⁻¹:** A peak in this region can suggest C-H bending, possibly from methyl groups.5. **1465.01 cm⁻¹:** This also relates to C-H bending, confirming the presence of aliphatic groups.6. **1058.55 cm⁻¹:** Generally associated with C-O stretching, likely indicating an ether or alcohol.### Interpretation:These peaks provide insight into the functional groups present in the molecule being analyzed. The spectral data can help characterize and identify unknown samples by comparing these peaks to known reference spectra. Understanding these kinds of absorption bands is crucial for fields such as organic chemistry and materials science. **Transcription for Educational Website****Instructions:**Assign the IR spectra given in Questions 1 - 3 to their corresponding structures from the ones below.**Molecular Structures:**1. Primary alcohol with an aldehyde group.2. Ethylbenzene.3. Triethylamine.4. An amide with a benzene ring.5. A long-chain alcohol with a ketone group.6. A nitrile group attached to a benzene ring.7. An amide with an isopropyl group.8. A bromoalkane.9. Benzoic acid.10. An aromatic ester.11. Hexanol.12. An anisole derivative.13. Ethylene glycol.14. Phenylacetylene.15. Isopropylbenzene.16. Acetone.17. Cyclohexanone.18. T-butyl alcohol.19. Acetophenone.Each structure contains unique functional groups that can be identified using infrared spectroscopy, such as O-H, C=O, C-N, C-Br, etc. Use the given IR spectra characteristics to match them to these structures based on the presence and intensity of peaks corresponding to these functional groups.**Note:** Diagrams contain only line structures of molecules without further elaboration on atomic labels or 3D conformation. Interpretation requires understanding of basic organic chemistry and IR spectroscopy.
