Draw the structural formula that is consistent with each of the 13CNMR spectra shown below
**Chemical Formula:** C₅H₁₀O₂ **Graph Explanation:** This graph represents an NMR (Nuclear Magnetic Resonance) spectrum of a compound with the chemical formula C₅H₁₀O₂. The x-axis is labeled "PPM" which stands for Parts Per Million, a unit used in NMR to denote chemical shifts. Here is a detailed explanation of the graph: 1. **X-Axis (Horizontal):** The PPM scale ranges from 0 to 200, specifically marked at intervals of 20 (0, 20, 40, 60, 80, 100, 120, 140, 160, and 180), which represents the chemical environment of the hydrogen atoms in the molecule. 2. **Y-Axis (Vertical):** This vertical axis usually represents the relative intensity of the signals detected. 3. **Peaks:** - There is a distinct peak present at around 180 PPM, suggesting a significant chemical shift. This location is typically associated with carbonyl carbons (e.g., carboxylic acids, esters, amides). - There are multiple peaks in the range from about 10 to 40 PPM. This suggests that there are multiple types of carbon environments in this range, most likely alkyl carbons (C-H). 4. **Chemical Information:** - The compound has a chemical formula of C₅H₁₀O₂, indicating it contains 5 carbon atoms, 10 hydrogen atoms, and 2 oxygen atoms. From the observations, this spectrum is indicative of a molecule containing both carbonyl and alkyl groups, a feature common in esters and carboxylic acids.
