Question

Consider the given chemical reaction :

Product ''A'' is :

• A. picric acid
• B. oxalic acid
• C. acetic acid
• D. adipic acid

Answer 1

The Correct Option is D

Reaction of cyclohexane with potassium permanganate (\(\text{KMnO}_4\)) and sulfuric acid (\(\text{H}_2\text{SO}_4\)) under heating oxidizes cyclohexane to adipic acid.
Step 1: Cyclohexane Oxidation
Cyclohexane (\(\text{C}_6\text{H}_{12}\)) is oxidized by \(\text{KMnO}_4\) in the presence of \(\text{H}_2\text{SO}_4\).
- \(\text{KMnO}_4\) converts the \(-\text{CH}_2-\) groups of cyclohexane into carboxylic acid (\(-\text{COOH}\)) groups.
- This process yields adipic acid (\(\text{HOOC} - (\text{CH}_2)_4 - \text{COOH}\)).
\[\text{C}_6\text{H}_{12} \rightarrow [\text{KMnO}_4, \text{H}_2\text{SO}_4, \text{Heat}] \text{HOOC} - (\text{CH}_2)_4 - \text{COOH} \, (\text{Adipic Acid})\]
Step 2: Conclusion  
The resulting product (Product A) is adipic acid.
Final Answer: (4).
