For the structure and 1H NMR spectrum shown below, match the labeled hydrogen atom groups on the molecule (A-F) with the corresponding signals in the spectrum.
For the structure and \( ^1H \) NMR spectrum shown below, match the labeled hydrogen atom groups on the molecule (A-F) with the corresponding signals in the spectrum. **Molecular Structure:** A molecule is depicted with labeled hydrogen atoms at different positions: - Group A: \(-\)\( \text{CH}_3 \) - Group B: \(-\)\( \text{CH}_ \) - Group C: \(-\)\( \text{CH}_2 \) - Group D: \(-\)\( \text{CH}_ \) - Group E: \(-\)\( \text{H} \) - Group F: \(-\)\( \text{CH}_3 \) **^1H NMR Spectrum:** The horizontal axis represents the chemical shift in parts per million (PPM). The spectrum features several distinct peaks: - A doublet at approximately 6.8 PPM with an integration of 1H, labeled "d" for doublet. - A multiplet near 5.0 PPM with an integration of 1H. - A doublet at approximately 3.4 PPM with an integration of 2H. - A doublet at approximately 2.3 PPM with an integration of 3H. - A multiplet near 1.8 PPM with an integration of 1H. - A doublet at approximately 1.0 PPM with an integration of 6H. **Explanation of Signals:** - **6.8 PPM (1H, d):** This peak is indicative of a hydrogen atom in an environment affected by electronegative atoms or groups. It corresponds to a specific coupling pattern due to neighboring hydrogens. - **5.0 PPM (1H, m):** This multiplet peak is typically seen for hydrogens in complex environments with multiple coupling partners. - **3.4 PPM (2H, d):** A doublet signal for two equivalent protons, possibly adjacent to an electronegative atom or group. - **2.3 PPM (3H, d):** A doublet indicating three equivalent protons, likely in a methyl group adjacent to the functional group inducing splitting. - **1.8 PPM (1H, m):** A multiplet for a single hydrogen atom in a complex environment. - **1.
