Question

Better results for the preparation of ethers X and Y can be obtained from reactant pairs respectively

• A.
• B.
• C.
• D.

Hint:

In ether synthesis, using a strong base like sodium ethoxide is key to generating a good yield of the product.

Answer 1

The Correct Option is B

For ether synthesis, the alkoxide anion attacks the alkyl halide in an \(\text{S}_\text{N}\)2 reaction mechanism to form the ether. In this case, using ethyl iodide (\(\text{CH}_3\text{CH}_2\text{Br}\)) with a strong base such as sodium ethoxide (\(\text{CH}_3\text{CH}_2\text{ONa}\)) can generate ethers efficiently. The second pair involves a reaction with bromine to form the desired ethers.
