Question

Which of the following compounds is obtained by Williamson synthesis ?

• A. only simple ethers
• B. only mixed ethers
• C. simple and mixed ethers.
• D. esters

Hint:

Williamson synthesis uses an alkoxide and an alkyl halide, so it gives both simple and mixed ethers.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept
In Williamson synthesis an alkoxide ion attacks an alkyl halide by SN2: \(\text{RONa} + \text{R'X} \rightarrow \text{ROR'} + \text{NaX}\).

Step 2: Detailed Explanation
If R and R' are the same, a simple (symmetrical) ether forms, for example diethyl ether from sodium ethoxide and ethyl bromide. If they differ, a mixed ether forms, for example ethyl methyl ether.
It does not give esters, so (D) is wrong, and it works for both types, so (A) and (B) are incomplete.

Final Answer:
It gives both simple and mixed ethers, option (C). \[ \boxed{\text{Simple and mixed ethers}} \]
