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)
Correct answer
D
(ii) > (iii) > (iv) > (i)

Solution

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).

Hence, the correct answer is option: 'D'.
