CH3-CH=CH2 + KMnO4 + H2SO4 + H2O → CH3-CH(OH)-CH2(OH) + K2SO4 + ↓ e ↓e ↑ MnSO4
-------- ↑
2e 5e

5 2
5 CH3-CH=CH2 + 2KMnO4 + 3H2SO4 + 2H2O → 5 CH3-CH(OH)-CH2(OH) + K2SO4 + 2MnSO4
proszę :)
C(-II) ---> C(-I) + e /*5
C(-I) ---> C(0) + e /*5
Mn(VII) + 5e ---> Mn(II) /*2
5CH₂=CH-CH₃ + 2KMnO₄ + 3H₂SO₄ + 2H₂O ---> 5 CH₂(OH)-CH(OH)-CH₃ + 2MnSO₄ + K₂SO₄
