Cyclohexene is heated with concentrated alkaline KMnOX4 and then acidified with HX3OX+. The organic product is
Ahexanedial
Bcyclohexane-1,2-diol
Ccyclohexanone
Dhexanedioic acid
Answer: D
Hot concentrated KMnOX4 cleaves the C=C bond, and each alkene carbon bearing H ends as COOH. Ring opening of cyclohexene thus gives HOOC−(CHX2)X4−COOH, hexanedioic (adipic) acid.
