Type: Assertion Reason-assertion-Hard-Class 12
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.
A
Both (A) and (R) are true and (R) is the correct explanation of (A).
B
Both (A) and (R) are true but (R) is not the correct explanation of (A).
C
(A) is true but (R) is false.
D
(A) is false but (R) is true.
