✔ 最佳答案
It seems like a question extracted from the CE pastpaper.1. Yes
Propene + oxidizing agent (acidified potassium permanganate) + water → diol
2. Yes
Sodium chloride (reducing agent: chloride ions) + acidified potassium permanganate(oxidizing agent: permanganate ions) + hydrogen ions (from solvent: water) → manganese(II) ions + chlorine + water
3. Yes
Ethanol + oxidizing agent (acidified potassium permanganate) → ethanoic acid + water

Acidified potassium permanganate is an oxidizing agent. The answer is 1 and 3. You should the equations in the text book of the chapter "alkene" and "alkanol".

2,3都得....
1.要鹼性既KMnO4先得
2.Cl- ->1/2Cl2+e-
3. KMnO4 KMnO4
CH3CH2OH------------->CH3CCHO----------------->CH3COOH
