AIIMS 2018 Chemistry Ether Synthesis MCQ Question

Option A is correct because it provides the appropriate reactants for ether synthesis through the Williamson ether synthesis method, which involves the reaction of an alkoxide ion with a primary alkyl halide. This reaction leads to the formation of an ether (R–O–R') via nucleophilic substitution.

In contrast, options B, C, and D may involve secondary or tertiary alkyl halides, which can lead to elimination reactions instead of substitution, or they may not provide the necessary alkoxide ion for the reaction to proceed effectively. Understanding the mechanism and selectivity of these reactions is crucial for successful ether synthesis.
