**Transcription for Educational Website** **Title**: Analyzing NMR Spectroscopy Data **Description**: In this exercise, an IR spectrum, a \(^{13}C\) NMR spectrum, and a \(^{1}H\) NMR spectrum were obtained for an unknown structure. The task is to draw the structure of this compound based on the given data. **Graph Explanation**: The image displays a \(^{1}H\) NMR spectrum with specific peaks at different chemical shifts. Here’s a detailed breakdown: - **Peaks and Chemical Shifts**: - A singlet at approximately 11 ppm corresponding to 1H, indicating the presence of a deshielded proton, possibly an acidic proton. - Peaks at around 7–8 ppm, each representing 2H, typically associated with aromatic protons. - A significant singlet at approximately 4 ppm corresponding to 3H, suggesting a -CH3 group possibly adjacent to an electronegative atom or group. - **X-axis (ppm)**: Parts per million, representing the chemical shift. - **Y-axis**: Intensity of the signal (not labeled but standard for such spectra). These insights will assist in deducing the possible structure of the compound based on its spectral data.

**Infrared Spectrum Analysis:** **Graph 1 - Infrared (IR) Spectrum:** - **X-axis:** Wavenumber (cm⁻¹) ranging from 4000 to 500 cm⁻¹. - **Y-axis:** Absorbance or transmittance (not labeled, typically shown in IR spectra). - **Description:** The IR spectrum displays several sharp peaks at various wavenumbers, indicating different molecular vibrations. High-intensity peaks appear around 3300, 2100, 1600, and 600 cm⁻¹, corresponding to specific functional groups or structural characteristics within the molecule being analyzed. **Graph 2 - Nuclear Magnetic Resonance (NMR) Spectrum:** - **X-axis:** Chemical shift (ppm) ranging from -10 to 180 ppm. - **Y-axis:** Intensity (not labeled, generally implies signal amplitude). - **Description:** The NMR spectrum features multiple peaks that represent different environments of nuclei (typically hydrogen or carbon) within the compound. Notable peaks are observed at approximately 170, 150, and 70 ppm, providing insight into the chemical structure and composition of the sample. These spectra are used in chemistry to determine the structural properties and molecular identity of substances, helping in research, quality control, and material verification.
