MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

The reaction between sodium methoxide ( CH _3 ONa ) and ethyl bromide ( CH _3 CH _2 Br ) is an example of Williamson ether synthesis. The methoxide ion ( CH _3 O ^ - ) acts as a nucleophile and attacks the primary alkyl halide ( CH _3 CH _2 Br ) via an S_N2 mechanism. The reaction proceeds as follows: CH _3 ONa + CH _3 CH _2 Br CH _3 OCH _2 CH _3 + NaBr The products formed are ethyl methyl ether and sodium bromide. Answer: Formation of CH _3 OCH _2 CH _3 + NaBr
