Question

From Williamson's synthesis preparation of which of the following is possible?

• A. Only symmetrical ethers
• B. Only asymmetrical ethers
• C. Both (a) and (b)
• D. None of the above

Answer 1

Answer: (C)

Both (a) and (b)

Answer 2

From Williamson's synthesis, both symmetrical and asymmetrical ethers can be prepared e.g., For synthesis of symmetrical ethers $CH_3 O^- Na^+ + BrCH_3 \longrightarrow ^{ CH_3OCH_3 }_{ dimethyl \, ether \, (symmetrical ether) } + NaBr$ For synthesis of asymmetrical ethers
