Question

The following compound can readily be prepared by Williamson ether synthesis by reaction between

• A.
• B.
• C.
• D.

Answer 1

Answer: (B)

Williamson ether synthesis is the reaction in which an alkyl halide is allowed to react with alkoxide to give ether. The reaction involves $S_{N}2$ attack of an alkoxide ion on primary alkyl halide. In option (a) and (b) there are alkoxide and alkyl halide, but option (b) is preferred because $I^{-}$ is better leaving group than $C{l}^{-}$.
