Per NCERT §9.3.6, mild oxidation of an alkene with cold dilute KMnO₄ (Baeyer's reagent) gives which product?
AA vicinal diol
BA ketone
CA carboxylic acid
DAn epoxide
Answer & Solution
Correct answer: A. A vicinal diol
NCERT §9.3.6: cold dilute KMnO₄ (Baeyer's reagent) adds two -OH groups across C=C → vicinal (1,2) diol. Decolourises violet KMnO₄.
