**Infrared (IR) Spectrum Analysis** **Which of the following compounds will have some of the characteristics of the IR spectrum below? Explain.** **IR Spectrum Details:** - **Transmittance (T%):** The y-axis represents transmittance percentages, ranging from 90% to 100%. - **Wavenumber (cm⁻¹):** The x-axis displays the wavenumber, ranging from approximately 2000 to 3500 cm⁻¹. **Key Absorption Peaks:** 1. **3087 cm⁻¹:** This peak is characteristic of C-H stretching in aromatic compounds. 2. **3033 cm⁻¹:** Another C-H stretching peak, typically seen in aromatic rings. 3. **2921 cm⁻¹:** C-H stretching in aliphatic compounds. 4. **1727 cm⁻¹:** A strong absorption band indicative of a C=O stretching vibration, commonly found in carbonyl groups. **Molecular Structures:** 1. **First Structure:** A brominated aromatic carboxylic acid. 2. **Second Structure:** A brominated aromatic ester. 3. **Third Structure:** A nitrogen-containing heterocyclic compound. **Analysis:** - The strong absorption at 1727 cm⁻¹ suggests the presence of a carbonyl group (C=O stretching), which is consistent with the first and second structures (carboxylic acid and ester). - The peaks around 3087 cm⁻¹ and 3033 cm⁻¹ indicate C-H stretching in aromatic compounds, present in all three structures. - The peak at 2921 cm⁻¹ reflects aliphatic C-H stretching, which may appear in the ester and the nitrogen-containing heterocycle. **Conclusion:** The IR spectrum provided matches the characteristics of compounds with aromatic rings, aliphatic C-H bonds, and a distinct carbonyl group. Both the first and second structures (the brominated aromatic carboxylic acid and ester) closely reflect these features.
