#### Graphs and their Descriptions

**Graph 7: Proton NMR of C₅H₁₀O**

- **Chemical Shifts (ppm):** Peaks are observed at approximately 0.9, 1.2, 1.4, 2.4, 3.6, and 9.4.
- **Peak Assignments:** Peaks labeled as 1, 5, and 2.
- **Notable Features:** Two peaks labeled as 2 appear as doublets, indicating a coupling pattern commonly seen with certain hydrogen environments.

**Graph 8: Proton NMR of C₈H₁₀O**

- **Chemical Shifts (ppm):** Peaks are observed around 1.3, 2.1, and 7.0.
- **Peak Assignments:** Peaks are labeled as 2 and 3.
- **Notable Features:** Most peaks seem to be singlets or doublets, suggesting a symmetrical hydrogen environment.

**Graph 9: Proton NMR of C₈H₁₀O**

- **Chemical Shifts (ppm):** Peaks are observed at approximately 0.9, 2.0, 4.0, and 7.3.
- **Peak Assignments:** Peaks are labeled as 1, 2, and 5.
- **Notable Features:** The peaks appear as singlets, indicating no coupling with adjacent hydrogen atoms.

**Graph 10: Proton NMR of C₆H₁₂O₂**

- **Chemical Shifts (ppm):** Peaks are observed at approximately 1.1, 2.3, 3.5, and 4.5.
- **Peak Assignments:** Peaks labeled as 1, 2, 3, and 6.
- **Notable Features:** The peaks exhibit various splitting patterns, indicative of coupling between neighboring protons in the molecule.

#### Question and Diagram

**Question 11:** Draw the expected ¹H NMR spectrum for the following compound.

- **Compound Structure:** The structure shown is an ether with substituents on either side of the oxygen atom.
- **Expected Features:** The expected NMR spectrum would include peaks corresponding to chemical shifts typical for ether environments, with possible multiplicity due to coupling.
