Question

Identify te following compounds based on the spectra given.

The image consists of four graphs, each representing different types of spectroscopic data commonly used in chemical analysis. 1. **Top Left Graph: Proton NMR Spectrum** - The graph displays a proton nuclear magnetic resonance (NMR) spectrum. - The x-axis is labeled "ppm" (parts per million), indicating chemical shift, which ranges from 0 to 10 ppm. - Peaks are present near 1, 2, 4, 5, and 7-8 ppm. - Integrations (noted as integral lines) above the peaks suggest the relative number of protons corresponding to each signal. 2. **Top Right Graph: Carbon-13 NMR Spectrum** - This graph shows a carbon-13 NMR spectrum. - The x-axis is labeled "ppm" and spans from 0 to 220 ppm. - Peaks appear around 20, 50, 80, 120, and 180 ppm. - These peaks correspond to the different carbon environments in the molecule. 3. **Middle Graph: Infrared (IR) Spectrum** - The IR spectrum is displayed with the x-axis labeled as "WAVENUMBER cm⁻¹," ranging from 4500 to 500 cm⁻¹. - The y-axis represents transmittance, decreasing from 100 to 0 percent. - Numerous peaks suggest various functional groups and bonds, with significant absorbance around 1600, 1400, and 1000 cm⁻¹, indicating possible carbonyl, aromatic, and C-H bonding regions. 4. **Bottom Graph: Mass Spectrum** - The graph presents a mass spectrum. - The x-axis shows the mass-to-charge ratio (m/z), ranging from 0 to 150. - The y-axis represents "relative intensity," ranging from 0 to 100%. - Significant peaks at m/z values of approximately 29, 55, 73, and 100 suggest fragment ions of the analyzed compound. These graphs provide a comprehensive insight into the molecular structure through various analytical techniques.
