Decreasing order of reactivity of the following compounds in the Williamson's ether synthesis is
- A (ii) > (iv) > (iii) > (i)
- B (i) > (ii) > (iii) > (iv)
- C (iv) > (iii) > (ii) > (i)
- D (ii) > (iii) > (iv) > (i)
Answer & Solution
Correct Answer
(D) (ii) > (iii) > (iv) > (i)
Step-by-step Solution
Detailed explanation
Williamson's ether synthesis occur through \(\mathrm{SN}^2\) mechanism. Option (i) is least stable due to steric hinderance of tertiary alkyl group. Therefore, the decreasing order of reactivity is (ii) \(>\) (iii) \(>\) (iv) \(>\) (i).
