**Elemental Composition and Spectral Analysis** - **Elemental Composition:** - Carbon (C): 30.29% - Hydrogen (H): 2.54% - Other Element: 67.17% **Graph and Diagram Analysis:** 1. **Mass Spectrometry Graph (Top):** - X-axis: Mass-to-charge ratio (m/z) - Y-axis: Relative Intensity - The graph shows several peaks at different m/z values, indicating the presence of ions with those mass-to-charge ratios. The most intense peak is usually referred to as the base peak. 2. **Infrared (IR) Spectroscopy Graph (Middle):** - X-axis: Wavenumber (cm⁻¹) - Y-axis: Percent Transmittance - The IR spectrum displays various peaks across the wavenumber range, indicating different vibrational modes of the molecular bonds present. The pattern and position of peaks give insights into functional groups within the compound. 3. **Nuclear Magnetic Resonance (NMR) Spectrum (Bottom):** - X-axis: Chemical Shift (ppm) - Peaks labeled as: - **2H, d:** Doublet with integration indicating 2 hydrogen atoms - **1H, t:** Triplet with integration indicating 1 hydrogen atom - The J-values mentioned are very small (2 Hz), indicating long-range coupling (more than 1 carbon away), showing the interaction between nuclear spins. This information is useful for determining the molecular structure and functional groups of the compound being analyzed. The combination of mass spectrometry, IR, and NMR provides a comprehensive view of the compound's characteristics.
