1. C4H8 has four isomers. A, B & Cgets reduced by KMnO4; D does not get reduced by
KMnO4. A forms an optically inactive mixture of two optically active forms in equal
amounts with acidified KMnO4 while B forms optically inactive meso form with
acidified KMnO4. Identify A, B, C & D. (Draw the structures of A, B, C & D with proper
explanation).
