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

### 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 (‡) | |-------------|---------------------|------------------|------|------|---------------------|------------------|------| | 1 | | | | 7 | | | | | 2 | | | | 8 | | | | | 3 | | | | 9 | | | | | 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
