NEET Chemistry Preparation MCQ Question
Which of the following statements about the preparation of ethers are correct?
Ethers can be synthesized through the dehydration of primary alcohols using acid.
Williamson's synthesis is suitable for preparing ethers from tertiary alcohols.
The main product of ethanol dehydration at high temperatures is ethene.
Secondary alcohol dehydration leads primarily to ether formation under specific conditions.
Correct Answer
Detailed Explanation
Ethers can indeed be synthesized through the dehydration of primary alcohols in the presence of protic acids, as indicated in the NCERT context. Williamson's synthesis is not suitable for tertiary alcohols due to steric hindrance, and the dehydration of ethanol at high temperatures typically favors ethene formation. Additionally, secondary alcohols are less favorable for ether formation compared to primary ones.
