Question:
Identify the product obtained when benzaldehyde is oxidized by \(\text{KMnO}_{4}\).
Identify the product obtained when benzaldehyde is oxidized by \(\text{KMnO}_{4}\).
Show Hint
Aldehydes are oxidised to carboxylic acids by strong oxidising agents.
Updated On: Nov 12, 2026
- Benzoic acid
- Benzyl alcohol
- Toluene
- Benzene
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
Aldehydes are easily oxidised to the corresponding carboxylic acids.
Step 2: Reaction
Benzaldehyde with \(\text{KMnO}_4\) gives benzoic acid:
\(\text{C}_6\text{H}_5\text{CHO}\xrightarrow{[O]}\text{C}_6\text{H}_5\text{COOH}\).
Step 3: Compare the options
Benzyl alcohol, toluene and benzene are reduction type products, so option (A) is correct.
Final Answer:
The product is benzoic acid. \[ \boxed{\text{(A) }\text{Benzoic acid}} \]
