### Infrared (IR) Spectroscopy: Compound Identification#### Question 12.2:**Which compound is consistent with the spectrum shown below?**#### Interpretation of the IR Spectrum:The provided IR spectrum is used to identify organic compounds based on their unique absorption patterns. **Axis Information:**- The x-axis represents the **wavenumber (cm-1)**, ranging from 4000 to 500 cm-1. The wavenumber is inversely proportional to wavelength, and it indicates the frequency at which the molecule absorbs IR light.- The y-axis represents **transmittance (%)**, which ranges from 0 to 100%. High transmittance means low absorption, and low transmittance means high absorption.**Key Features in the Spectrum:**1. **Broad Peaks around 3200-3600 cm-1:** - Indicative of O-H or N-H stretching.2. **Strong Peak near 1700 cm-1:** - Indicative of C=O (carbonyl) stretching.3. **Multiple Peaks in the Fingerprint Region (1500-500 cm-1):** - Useful for identifying specific functional groups and overall match with compounds but generally more complex.#### Compounds to Consider:Below the spectrum, five structural formulas of organic compounds are provided as potential matches:1. **Compound (a):** An aliphatic compound with a double bond.2. **Compound (b):** An alcohol.3. **Compound (c):** A carboxylic acid.4. **Compound (d):** An amine.5. **Compound (e):** An ester.#### Analysis:Given the broad peak around 3200-3600 cm-1, this suggests the presence of an O-H group or N-H group. The strong peak near 1700 cm-1 indicates the presence of a carbonyl group (C=O).**Conclusion:**Based on the IR spectrum, the compound is consistent with the presence of both an O-H group (broad peak around 3200-3600 cm-1) and a carbonyl group (sharp peak around 1700 cm-1). Therefore, the compound most consistent with the spectrum is **Compound
