### Infrared (IR) Spectrum AnalysisThe IR spectrum provided gives an insight into the functional groups present within a chemical compound. The x-axis represents the wavelength in wavenumbers (cm⁻¹), ranging from 4000 cm⁻¹ to 500 cm⁻¹, whereas the y-axis shows percent transmittance, ranging from 0% to 100%.**Key Absorption Peaks:**1. **3283 cm⁻¹**: This strong, broad absorption band is characteristic of N-H stretching vibrations, typically found in primary amines.2. **2966 cm⁻¹**: This peak corresponds to C-H stretching vibrations, which are common in many organic compounds.3. **2814 cm⁻¹**: This band can indicate aldehyde C-H stretching.4. **1452 cm⁻¹ and 1379 cm⁻¹**: These peaks are often due to bending vibrations of -CH2- and -CH3 groups.5. **1327 cm⁻¹**: This absorption can be linked to the presence of C-N stretching, common in amines.6. **1181 cm⁻¹, 1093 cm⁻¹**: These peaks are typically associated with C-N stretching vibrations, providing further evidence of amines.7. **1119 cm⁻¹**: Another C-N stretching band indicative of amines.8. **1047 cm⁻¹**: This is generally a C-O stretching vibration, found in alcohols and ethers.9. **727 cm⁻¹**: This peak can be attributed to aromatic C-H bending.### Question Analysis- **Question:** Is this IR spectrum consistent with the structure of an alcohol, a ketone, a carboxylic acid, a primary amine, or a secondary amine?### Interpretation:The presence of a strong N-H stretch around 3283 cm⁻¹ and multiple C-N stretching peaks strongly suggest that the compound is an amine. Specifically:- The **3283 cm⁻¹** peak indicates an N-H stretch, supporting the presence of a primary amine.- Multiple peaks between **1300 cm⁻¹ and 1200 cm⁻¹** align with C-N stretching vibrations.Based on the IR spectrum features discussed, the analyzed compound is most consistent with the structure of a **primary amine**.
