EXPLAIN INFRARED UNKNOWN. . **Infrared Spectrum Analysis**This image depicts an infrared (IR) spectrum graph. The vertical axis represents transmittance, ranging from 0 to 1, while the horizontal axis shows the wavenumber, measured in cm⁻¹, ranging from approximately 4000 to 600.**Graph Details:**- **Transmittance:** Indicates how much of the infrared light passes through the sample. A value close to 1 means most light is transmitted, and lower values indicate absorption at specific frequencies. - **Wavenumber:** Reflects the frequency of the infrared light, with higher wavenumbers corresponding to higher energy vibrations within the molecule.The graph shows various peaks indicating different vibrational modes of a molecule. The major absorptions occur in several regions, such as around 3000 cm⁻¹, 1600 cm⁻¹, and below 1000 cm⁻¹, which are characteristic of different functional groups.**Source:**NIST Chemistry WebBook (https://webbook.nist.gov/chemistry)

To explain the given INFRARED SOECTRUMInfrared spectrum helps to determine the functional group present in the compound. C-H stretch is observed in the range of 2800-2900 cm-1. This implies the presence of sp3 C atom Peak at 3300 cm-1 indicates the presence of secondary amine. So, using the given IR spectrum, we can say that the functional group present in the compound is SECONDARY AMINE
