### Proton Deprotonation Activity

**Question:**  
The most acidic proton on the molecule below has a \( pK_a \) of 41. Which of the following bases are capable of deprotonating the proton? Check all that apply.

**Note:** Reference the \( pK_a \) of selected organic compounds table for additional information.

#### Table: \( pK_a \) Values of Selected Acids

| Acid       | \( pK_a \) Value |
|------------|------------------|
| \( \text{CH}_3\text{CH}_2\text{OH} \) | 16               |
| \( \text{H}_2\text{CO}_3 \)          | 6.4              |
| \( \text{H}_2\text{O} \)             | 14               |
| \( \text{H}_2 \)                     | 35               |
| \( \text{C}_4\text{H}_{10} \)        | 50               |

#### Explanation:

In the table provided, each row lists an acid along with its corresponding \( pK_a \) value. The objective is to determine which bases (conjugate bases of the acids listed) can deprotonate a proton with a \( pK_a \) of 41. A base can deprotonate the proton if its conjugate acid has a lower \( pK_a \) value than 41 because it indicates a stronger acid.

#### Graphical Element:

- **Diagram:** There is a hexagonal structure representing a benzene ring with an additional line indicating a substituent group, which is likely a part of the molecule discussed.

**Analysis:**

- Ethanol (\( \text{CH}_3\text{CH}_2\text{OH} \)), Carbonic acid (\( \text{H}_2\text{CO}_3 \)), and Water (\( \text{H}_2\text{O} \)) all have \( pK_a \) values considerably lower than 41, making their conjugate bases strong enough to deprotonate the benzene-ring molecule’s proton.
- Hydrogen (\( \text{H}_2 \)) with a \( pK_a \) of 35 is also capable of deprotonating the proton.
- Butane (\( \text{C}_4\text{H}_{10
