Question

please answer this spec question! answer choices are given except toluene and tetrahydrofuran! 

This image is an infrared (IR) spectrum graph, displaying the transmittance (%T) against the wavenumber (cm⁻¹). The horizontal axis represents the wavenumber, ranging from 4000 to 500 cm⁻¹, while the vertical axis shows percentage transmittance, ranging from 0 to 85%. Key absorption peaks are observed at the following wavenumbers: - **3398.81 cm⁻¹**: Often indicative of O-H or N-H stretching, common in alcohols and amines. - **2971.22 cm⁻¹**, **2910.00 cm⁻¹**, **2874.39 cm⁻¹**: Typically associated with C-H stretching in alkanes. - **1708.77 cm⁻¹**: Commonly corresponds to C=O stretching found in carbonyl groups like ketones and esters. - **1477.87 cm⁻¹**: A potential C-H bending vibration often seen in methylene groups. - **1355.71 cm⁻¹**: Could be related to C-H bending or a possible coupling with other vibrations. - **1136.84 cm⁻¹**: Might indicate C-O stretching, typical in alcohols, esters, or ethers. - **954.51 cm⁻¹**: Can be associated with a variety of bending vibrations depending on the molecular context. This spectrum helps in identifying functional groups present in the compound being analyzed, crucial for understanding the molecular structure.
