### Identifying Compounds from Spectra This educational section focuses on identifying chemical compounds using various spectroscopic techniques. Below, we explain the elements of each spectral analysis provided in the image. #### Graph Descriptions 1. **Proton NMR Spectrum (Top Left)** - **x-axis:** Chemical shift (ppm) from 0 to 4. - **Features:** Several peaks indicating the presence of hydrogen atoms in different environments within the molecule. The chemical shifts and splitting patterns can help deduce the structure of the compound. 2. **Carbon-13 NMR Spectrum (Top Right)** - **x-axis:** Chemical shift (ppm) from 0 to 220. - **Features:** Peaks at various points along the x-axis, indicating the environments of carbon atoms within the molecule. The number of peaks can give an indication of the different carbon environments present. 3. **Infrared (IR) Spectrum (Middle)** - **x-axis:** Wavenumber (cm⁻¹) from 4000 to 500. - **Features:** Several absorption peaks across the spectrum. Key peaks can indicate functional groups present in the compound, based on the characteristic absorption frequencies of different bonds. 4. **Mass Spectrum (Bottom)** - **x-axis:** Mass-to-charge ratio (m/z) from 0 to 100. - **Features:** A large peak indicative of the molecular ion, along with various smaller peaks representing fragment ions. This spectrum can give insights into the molecular weight and structural fragments of the compound. These spectral analyses are crucial in determining the molecular structure and identifying unknown compounds in chemistry. Understanding and interpreting these graphs can provide insights into the functional groups, carbon skeleton, and overall molecular architecture.
