Alkenes on reaction with cold, dilute, aqueous solution of potassium permanganate (Baeyer's reagent) produce vicinal glycols. Decolorisation of KMnO 4 solution is used as a test for unsaturation.

Q. Choose the correct option regarding $A$ and $B$ .
$C H_{2} = C H_{2} + H_{2} O + [O] Dil. K M n O_{4} 273 K A$
