Question

how propene reacts with dilute KMnO4 solution give equations

Answer 1

Propene reacts with dilute KMnO4 solution to give propane 1,2 diol.

• The equation of the following is as follows:-

• CH3CH=CH2 → CH3CHOH-CH2OH
• Mechanisms: 1.Potassium permanganate adds to one face of the alkene through a cycloaddition reaction to give a cyclic manganese compound (“manganate ester”).
• The manganate ester is then reduced with NaHSO3 or KHSO3 and hydrolyzed to the diol.
