Question

Which one of the following does not form peroxide easily?

• A. Diethyl ether
• B. Ethylmethyl ether
• C. Dimethyl ether
• D. Anisole

Answer 1

Answer: (D)

Anisole

Oxygen atom is strongly bonded to the benzene ring. so, anisole can not easily form peroxides.

But diethyl ethers easily form peroxides in air.

Anisole does not form peroxide easily as it is an aryl alkyl ether. On the other hand, diethyl ether, ethylmethyl ether and dimethyl ether are aliphatic ether and easily form peroxides.
