An organic compound 'A' C4H8 on treatment with KMnO4/H+ yields compound 'B' C3H6O. Compound 'A' also yields 'B' on ozonolysis. Compound 'A' is:

1. 2-Methylpropene
2. 1-Methylcyclopropane
3. But-2-ene
4. Cyclobutane

Correct answer: 2-Methylpropene

Solution

2-Methylpropene is an alkene that can undergo oxidation with KMnO4 to form a ketone, which matches the formula of compound 'B' (C3H6O). Additionally, ozonolysis of 2-Methylpropene also yields the same compound 'B', confirming it as the correct structure for compound 'A'.
