Question:
Identify the product obtained when alkenes are oxidised with \(\mathrm{KMnO}_4\) in dil. \(\mathrm{H}_2 \mathrm{SO}_4\).
Identify the product obtained when alkenes are oxidised with \(\mathrm{KMnO}_4\) in dil. \(\mathrm{H}_2 \mathrm{SO}_4\).
Show Hint
Hot or acidic KMnO4 cleaves the double bond and oxidises the fragments to carboxylic acids or ketones.

- Alkanone
- Alkanoic acid
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Acidified potassium permanganate is a strong oxidising agent which cleaves the C=C double bond of alkenes.
Step 2: Fragments
Each fragment is oxidised further: a CH-type end becomes a carboxylic acid and a disubstituted end becomes a ketone.
Step 3: Result
Among the given options, the product is the alkanoic acid.
Final Answer:
The product is an alkanoic acid. \[ \boxed{\text{(D) }\text{Alkanoic acid}} \]
