Question:
An aldehyde on oxidation gives
An aldehyde on oxidation gives
Show Hint
Aldehydes are oxidized to carboxylic acids, while alcohols are reduced to aldehydes.
Updated On: Oct 16, 2025
- an alcohol
- a ketone
- an ether
- an acid
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the oxidation of aldehydes.
Aldehydes are oxidized to carboxylic acids when they react with oxidizing agents. The oxidation involves the conversion of the aldehyde group (-CHO) to a carboxyl group (-COOH), forming an acid. Step 2: Analysis of options.
(A) an alcohol: Aldehydes are not typically oxidized to alcohols; they are reduced to alcohols instead.
(B) a ketone: Aldehydes are not oxidized to ketones; ketones are already oxidized compounds.
(C) an ether: Aldehydes do not oxidize to form ethers. Ethers are formed by different processes, such as dehydration reactions.
(D) an acid: Correct — Aldehydes are oxidized to carboxylic acids.
Step 3: Conclusion.
The correct answer is (D) because the oxidation of an aldehyde results in the formation of a carboxylic acid.
