An Alkene " X " on reaction with hot acidified \(\mathrm{KMnO}_4\) gave a mixture of Ethanoic acid and Propanone. Identify " X ".
- A But-2-ene
- B Pent-2-ene
- C 2- Methylbut-2-ene.
- D 2,3 -Dimethylbut-2-ene
Answer & Solution
Correct Answer
(C) 2- Methylbut-2-ene.
Step-by-step Solution
Detailed explanation
The reaction of an alkene with hot acidified \(\mathrm{KMnO}_4\) results in oxidative cleavage of the carbon-carbon double bond. The products formed depend on the substitution pattern at the double bond carbons. Ethanoic acid is \(\mathrm{CH}_3\mathrm{COOH}\), which corresponds…
