Помогите с химией пожалуйста !!!!

СН3–СН2–СН3 + Br2 → СН3–СНBr–СН3 + HBr,
2СН3–СНBr–СН3 + 2Na → (CH3)2CH–CH(CH3)2 + 2NaBr.


(CH3)2CH–CHCl2 + 2NaOH → (CH3)2CH–C(О)H + 2NaCl + H2O,
(CH3)2CH–C(О)H + 2NaMnO4 +3NaOH → (CH3)2CH–COONa + 2Na2MnO4 + 2H2O,
2(CH3)2CH–COONa + 2H2O → (CH3)2CH–CH(CH3)2 + 2CO2 + 2NaOH + H2.
