CH3-CH=CH-CH2-CH2-CH3+[O]+H2O⇒CH3-CH(OH)-CH(OH)-CH2-CH2-CH3
2KMnO4 + H2O ⇒ 2KOH + 2MnO2 + 3[O]
CH3-CH=CH-CH2-CH2-CH3 + 4[O] ⇒ CH3COOH + CH3-CH2-CH2-COOH
2KMnO4 + 3H2SO4 ⇒ K2SO4 + 2MnSO4 + 3H2O + 5[O]
CH3-(CH3)C=CH-CH2-CH3 +[O] + H2O ⇒ diol
CH3-(CH3)C=CH-CH2-CH3 + 3[O] ⇒ CH3-CO-CH3 + CH3-CH2-COOH
2,3 dimetil butan ≠ alchena ; nu se oxideaza;
CH3-(CH3)C=C(CH3)-CH3 + 2[O] ⇒2 CH3-CO-CH3
CH3-(CH3)C=C(CH3)-CH3 + [O] + H2O ⇒diol
- la toate oxidarile blande : n KMnO4 / n alchena = 2/3
- la oxidarile energice : n1KMnO4 /n alchena = 8/5
n2KMnO4/ nalchena = 6/5 ; n3KMnO4/n alchena = 4/5
