NEET Chemistry Preparation MCQ Question
Which of the following statements about the preparation of ethers is correct?
Ethers can be prepared by the dehydration of primary alcohols using acid.
Williamson's synthesis is effective for all types of ethers regardless of the alcohol used.
Secondary alcohols can be dehydrated to form ethers without producing alkenes.
The acidic dehydration of tertiary alcohols is the preferred method for ether synthesis.
Correct Answer
Detailed Explanation
Ethers can indeed be prepared by the dehydration of primary alcohols in the presence of an acid. Williamson's synthesis is not effective for all ethers, particularly those involving secondary or tertiary alcohols, due to steric hindrance and competing reactions.
