Question

Based on the IR spectrscopy,  identify if the liquid compound is 3-methyl-3-buten-1-ol, 1-octene, decane, benzophenone, cyclohexanol, benzoic acid, vanilin, or lidocaine?

The image shows an infrared (IR) spectrum plotted on a graph. The x-axis represents the wavenumber in cm⁻¹, ranging from around 4000 cm⁻¹ (left) to 500 cm⁻¹ (right). The y-axis is typically the transmittance or absorbance, indicating how much IR radiation is absorbed by a sample at each wavenumber. ### Description of the Spectrum: 1. **Range from 3500 to 4000 cm⁻¹**: - The plot is relatively flat with a slight dip, suggesting low absorption, typically indicative of O-H or N-H stretching vibrations. 2. **Range from 3000 to 2000 cm⁻¹**: - The graph remains mostly flat with minor fluctuations, which is characteristic of C-H stretching in alkanes and alkenes. 3. **Range from 2000 to 1500 cm⁻¹**: - There are sharp peaks, indicating higher absorption, possibly due to C≡C or C≡N stretching vibrations. 4. **Range from 1500 to 500 cm⁻¹**: - The graph shows multiple sharp, high-intensity peaks, representing the fingerprint region unique to each molecule. These peaks could arise from complex combinations of bending, stretching, and wagging vibrations in various functional groups. This IR spectrum can help identify functional groups within a molecule and provide insights into its molecular structure.
