NEET Chemistry Preparation MCQ Question

Type: MCQ-conceptual-Medium-Class 12

Which of the following combinations correctly describes the preparation of ethers from alcohols?

A

Ethers can be prepared by dehydration of primary alcohols and involve an S_N2 mechanism.

B

Secondary alcohols are ideal for ether formation through acidic dehydration.

C

The dehydration of alcohols to form ethers is always the preferred method over Williamson synthesis.

D

Ethers can only be formed at high temperatures during dehydration of alcohols.

Correct Answer

Option A

Detailed Explanation

Ethers can indeed be prepared by the dehydration of primary alcohols, which follows an S_N2 mechanism as stated in the NCERT context. Secondary alcohols are not suitable for this method, and while dehydration can occur at various temperatures, it does not limit ether formation solely to high temperatures.
