Question

Consider the given chemical reaction :

Product ''A'' is :

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

Answer 1

Answer: (D)

adipic acid

Answer 2

The reaction of cyclohexane with potassium permanganate ($\text{KMnO}_4$) in an acidic medium ($\text{H}_2\text{SO}_4$) and heat results in the oxidation of cyclohexane to adipic acid.
Step 1: Oxidation of cyclohexane
Cyclohexane ($\text{C}_6\text{H}_{12}$) undergoes oxidation in the presence of $\text{KMnO}_4$ and $\text{H}_2\text{SO}_4$.
- The $\text{KMnO}_4$ oxidizes the $-\text{CH}_2-$ groups in cyclohexane to carboxylic acid ($-\text{COOH}$) groups.
- This results in the formation of 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 product $A$ is adipic acid.
Final Answer: (4).
