NEET Chemistry Preparation Assertion Reason Question
Assertion (A): Williamson synthesis is suitable for the preparation of ethers with primary alkyl groups.
Reason (R): Acidic dehydration of secondary or tertiary alcohols is not a suitable method for ether preparation.
Both (A) and (R) are true and (R) is the correct explanation of (A).
Both (A) and (R) are true but (R) is not the correct explanation of (A).
(A) is true but (R) is false.
(A) is false but (R) is true.
Correct Answer
Detailed Explanation
Williamson synthesis is effective for primary alkyl groups due to its nucleophilic substitution mechanism, while the acidic dehydration method is unsuitable for secondary and tertiary alcohols because it leads to alkenes instead of ethers.
