What are the following values for 3-ethyloxy-1-butene NMR in the attached table

Transcribed Image Text:### Proton Nuclear Magnetic Resonance (¹H NMR) Data Table
#### Understanding the Table:
The table below is used to record and analyze ¹H NMR spectroscopy data. This is essential for identifying the structure of organic compounds based on the environment of hydrogen atoms within the molecule. Each row corresponds to a different peak observed in the NMR spectrum.
#### Data Recording:
| ¹H NMR Peak | Chemical Shift (δ) | Multiplicity (†) | H (‡) | Peak | Chemical Shift (δ) | Multiplicity (†) | H (‡) |
|-------------|---------------------|------------------|------|------|---------------------|------------------|------|

| 4 | | | | 10 | | | |
| 5 | | | | 11 | | | |
| 6 | | | | 12 | | | |
**Table Legends:**
- **Chemical Shift (δ):** This is the resonance frequency of the hydrogen atoms, measured in parts per million (ppm). It indicates the chemical environment of the hydrogens.
- **Multiplicity (†):** This indicates the splitting pattern of each peak which can be due to spin-spin coupling with neighboring hydrogens. Specific multiplicities include:
- Singlet (s)
- Doublet (d)
- Triplet (t)
- Quartet (q)
- Multiplet (m)
- **H (‡):** The number of hydrogens associated with each peak, which helps in determining the integration and quantifying the signal.
#### Notations:
- † Specify the multiplicity as a singlet (s), doublet (d), triplet (t), quartet (q), or multiplet (m).
- ‡ Specify the number of hydrogens associated with each peak.
#### Application:
Understanding and utilizing this table enables students and chemists to:
1. Record NMR spectra efficiently.
2. Analyze the data to elucidate the molecular structure.
3. Identify functional groups and
