+ Brz (red) (Eq. 3) Br Br 1,2-dibromo compound (colorless) A potassium permanganate (KMnO4) solution can oxidize a double bond at room temperature to form a 1,2-diol with the simultaneous reduction of Mn' in KMnO4 to Mn** in manganese dioxide (MnO2), as shown in Equation 4. A positive test is the disappearance of the purple KMnO4 and the appearance of MnO2 as a muddy brown precipitate. + 2 KMnO4 + 4 H2O — Но + 2MnO2 + 2 KOH он (brown) (Eq. 4) (purple) 1,2 diol
