\(n\)-pentane and isopentane can be distinguished by
- A \(\mathrm{Br}_2\)
- B \(\mathrm{O}_3\)
- C conc. \(\mathrm{H}_2 \mathrm{SO}_4\)
- D \(\mathrm{KMnO}_4\)
Answer & Solution
Correct Answer
(D) \(\mathrm{KMnO}_4\)
Step-by-step Solution
Detailed explanation
\(\mathrm{KMnO}_4\) oxidises \(3^{\circ} \mathrm{H}\) of isopentane to \(3^{\circ}-\mathrm{OH}\) group. As a result, pink violet colour of \(\mathrm{KMnO}_4\) get discharged. In constants, \(1^{\circ}\) or \(2^{\circ} \mathrm{H}\) of \(n\)-pentane does not get oxidised to the…
