Question

When ethyl bromide is treated with dry silver oxide, then we get

• A. Diethyl ether
• B. Ethanal
• C. Ethane
• D. Ethene

Hint:

Dry silver oxide (Ag₂O) is used in the synthesis of ethers from alkyl halides through a nucleophilic substitution reaction.

Answer 1

The Correct Option is A

Step 1: Understanding the reaction with dry silver oxide.
When alkyl halides like ethyl bromide are treated with dry silver oxide, they undergo a nucleophilic substitution, leading to the formation of an ether. Step 2: Analysis of options.
(A) Diethyl ether: Correct — The reaction of ethyl bromide with dry silver oxide produces diethyl ether.
(B) Ethanal: This is incorrect; ethanal is not formed in this reaction.
(C) Ethane: This is incorrect; ethane is not produced when silver oxide is used.
(D) Ethene: This is incorrect; ethene is formed under different conditions (e.g., elimination).
Step 3: Conclusion.
The correct answer is (A) because the reaction of ethyl bromide with dry silver oxide results in the formation of diethyl ether.
