JEE Main Chemistry question

Which of the following reactions does not yield an ether?

(A)Sodium methoxide reacts with dimethyl sulphate
(B)Sodium ethoxide reacts with ethyl bromide
(C)Sodium ethoxide reacts with bromocyclopentaneCorrect
(D)Ethanol reacts with in presence of

Answer: (C)

Solution

Bromocyclopentane is a secondary cyclic halide; with a basic/nucleophilic alkoxide like sodium ethoxide, the bulky secondary substrate favours E2 elimination (forming cyclopentene) over substitution, so no ether forms. The
