Ether is obtained from ethyl alcohol

Options

A. 113K
B. 443K
C. 413 K
D. 213 K

Answer

To obtain ether from ethyl alcohol (ethanol), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactant we are using is ethyl alcohol (ethanol), which has the chemical formula \( \text{C}_2\text{H}_5\text{OH} \).

2. **Choose the Reaction Conditions**:
- We need to perform the reaction in the presence of an acid catalyst. In this case, sulfuric acid (\( \text{H}_2\text{SO}_4 \)) is commonly used.

3. **Determine the Temperature**:
- The reaction to form ether from ethyl alcohol is temperature-dependent. We need to select a temperature that allows for the formation of diethyl ether. The suitable temperature for this reaction is 413 Kelvin.

4. **Reaction Mechanism**:
- At 413 Kelvin, the reaction proceeds via an \( \text{S}_N2 \) mechanism. This involves the nucleophilic substitution where one molecule of ethyl alcohol acts as a nucleophile and attacks another molecule of ethyl alcohol in the presence of the acid catalyst.

5. **Write the Reaction**:
- The overall reaction can be represented as:
\[ 2 \text{C}_2\text{H}_5\text{OH} \xrightarrow{\text{H}_2\text{SO}_4, 413 \text{ K}} \text{C}_2\text{H}_5\text{O}\text{C}_2\text{H}_5 + \text{H}_2\text{O} \]
- The product formed is diethyl ether (\( \text{C}_2\text{H}_5\text{O}\text{C}_2\text{H}_5 \)).

6. **Conclusion**:
- Therefore, the correct temperature at which ether is obtained from ethyl alcohol is 413 Kelvin.

### Final Answer:
The temperature at which ether is obtained from ethyl alcohol is **413 Kelvin**.
