When ethyl bromide is treated with moist `Ag_(2)O` main product is//are.

Options

A. Ethyl ether
B. Ethanol
C. Ethoxy ethane
D. All of the above

Explanation

To solve the question of what happens when ethyl bromide is treated with moist Ag₂O, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactant is ethyl bromide, which has the chemical formula \( \text{C}_2\text{H}_5\text{Br} \) (or \( \text{CH}_3\text{CH}_2\text{Br} \)).
- The other reactant is moist silver oxide, \( \text{Ag}_2\text{O} \), which in the presence of moisture (water) will form silver hydroxide \( \text{AgOH} \).

2. **Understand the Reaction**:
- When ethyl bromide reacts with moist silver oxide, the silver hydroxide \( \text{AgOH} \) will react with the bromide ion from ethyl bromide.
- This reaction is a nucleophilic substitution reaction where the hydroxide ion (\( \text{OH}^- \)) from \( \text{AgOH} \) replaces the bromine atom in ethyl bromide.

3. **Write the Reaction**:
- The reaction can be represented as:
\[ \text{C}_2\text{H}_5\text{Br} + \text{AgOH} \rightarrow \text{C}_2\text{H}_5\text{OH} + \text{AgBr} \]
- Here, \( \text{C}_2\text{H}_5\text{OH} \) is ethanol, and \( \text{AgBr} \) is silver bromide, which is the side product.

4. **Identify the Main Product**:
- The main product of this reaction is ethanol (\( \text{C}_2\text{H}_5\text{OH} \)).
- The side product formed is silver bromide (\( \text{AgBr} \)).

5. **Conclusion**:
- Therefore, when ethyl bromide is treated with moist Ag₂O, the main product is ethanol.

### Final Answer:
The main product when ethyl bromide is treated with moist Ag₂O is **ethanol (C₂H₅OH)**.
