The preparation of ethers from alcohols by using sulphuric acid is called as __________

Options

A. Williamson's ether synthesis
B. continuous etherification process
C. diazomethane method
D. Wurtz synthesis

Answer

To answer the question, "The preparation of ethers from alcohols by using sulphuric acid is called as __________," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Reaction**: The preparation of ethers from alcohols involves a dehydration reaction where water is removed from alcohols in the presence of an acid catalyst.

2. **Identify the Acid Catalyst**: In this case, sulfuric acid (H₂SO₄) is used as the acid catalyst to facilitate the reaction.

3. **Recognize the Process**: The specific process that involves the conversion of alcohols to ethers using sulfuric acid is known as the "continuous etherification process."

4. **Explain the Mechanism**: During the continuous etherification process, alcohol reacts with sulfuric acid to form an intermediate compound (like ethyl hydrogen sulfate). This intermediate then reacts with another molecule of alcohol to produce the ether and regenerate the sulfuric acid.

5. **Conclude the Answer**: Therefore, the correct term for the preparation of ethers from alcohols using sulfuric acid is the "continuous etherification process."

### Final Answer:
The preparation of ethers from alcohols by using sulphuric acid is called as **continuous etherification process**.
