**Which compound below fits the following 1H NMR data?** **NMR Spectrum Analysis:** This image represents a proton nuclear magnetic resonance (^1H NMR) spectrum. The x-axis displays the chemical shift in parts per million (ppm). The spectrum exhibits the following peaks: 1. **3H Singlet:** Appears at approximately 3.6 ppm. This indicates three equivalent hydrogen atoms are present which do not couple with adjacent hydrogens. 2. **2H Singlet:** Appears at approximately 4.2 ppm. This indicates two equivalent hydrogen atoms that appear as a singlet, suggesting isolation from other H atoms. 3. **3H Singlet:** Appears at approximately 1.2 ppm. Similar to the first peak, this also indicates three equivalent hydrogen atoms as a singlet. These signals suggest the presence of functional groups and structural information about the molecule being studied. The singlets suggest that these protons are not splitting, meaning they are not adjacent to any other hydrogen atoms that would cause splitting patterns.

The image depicts four chemical structures labeled A, B, C, and D. Here are the chemical formulas for each structure: A) CH₃CH₂COCH₃ - This structure represents a ketone with a ketone group (C=O) in the middle and is flanked by ethyl (CH₃CH₂) and methyl (CH₃) groups. B) CH₃COCH₂CH₃ - Another ketone, this one features the ketone group (C=O) positioned between a methyl (CH₃) and an ethyl (CH₂CH₃) group. C) H₂C=C(CH₃)OCH₃ - This structure is an ether with a methoxy group (OCH₃) attached to an alkene. The double bond is between the two carbon atoms, one of which also has a methyl group (CH₃). D) CH₃CCH₂OCH₃ - This structure is an ether with a methoxy group attached to a chain of carbon atoms that includes an acetyl group (CH₂O). These structures illustrate different organic compounds, emphasizing the diverse arrangements of functional groups such as ketones, ethers, and alkenes.
