### 'H NMR Spectrum Analysis

The table below analyzes the ^1H NMR spectrum of an unknown compound G, with a molecular formula of C<sub>7</sub>H<sub>14</sub>O. The data presents chemical shifts, integration, multiplicity, and the number of neighboring hydrogen atoms, which help identify the partial structure.

| δ (ppm) | Integration | Multiplicity | # of Neighboring H | Partial Structure |
|---------|-------------|--------------|--------------------|-------------------|
| 2.08    | 2           | Doublet      | 1                  |                   |
| 9.58    | 9           | Singlet      | 0                  |                   |
| 3.00    | 3           | Triplet      | 2                  |                   |

### ^13C NMR Spectrum Analysis

The table below should be completed using the ^13C NMR spectrum for the same unknown compound G. Each signal is assigned to a partial structure.

| Partial Structure | Partial Structure |
|-------------------|-------------------|
| a                 | d                 |
| b                 | e                 |

### Structural Assignment

- **Hydrogen Assignments:** Assign the hydrogen signals (A-C) to the appropriate protons in the molecule.
- **Carbon Assignments:** Assign the carbon signals (a-e) to the corresponding carbon atoms in the molecule's structure.

### NMR Spectra Explanation

#### ^1H NMR Spectrum for C<sub>7</sub>H<sub>14</sub>O:

- The spectrum shows three distinct peaks:
  - **Peak A**: At 2.08 ppm, with an integration of 2 generating a doublet, indicating a hydrogen atom next to one other hydrogen.
  - **Peak B**: At 9.58 ppm, with an integration of 9 and a singlet, suggesting the presence of a isolated hydrogen environment without neighboring hydrogens.
  - **Peak C**: At 3.00 ppm, with an integration of 3 producing a triplet, indicative of hydrogen atoms adjacent to two other hydrogens.

#### ^13C NMR Spectrum for C<sub>7</sub>H<sub>14</sub>O:

- The spectrum includes several peaks labeled a to e:
  - **Peak a** begins near 220 ppm.
  - Additional peaks labeled b, c,
