✔ 最佳答案
1.Mix ethene with hydrogen bromide.
CH₂=CH₂ + HBr → CH₃‒CH₂Br
2.
Mix ethene gas with chlorine gas and chlorine gas or chlorine solution.
CH₂=CH₂ + Cl₂ → CH₂Cl‒CH₂Cl
3.
Shake ethene gas with potassium dichromate solution acidified with dilute sulfuric acid.
5CH₂=CH₂ + 2KMnO₄ + 3H₂SO₄ + 2H₂O → 5CH₂OH-CH₂OH + K₂SO₄ + Mn₂(SO₄)₃

1. Add Hydrogen Bromide ; HBr + CH2=CH2 => CH3-CH2Br
2. Add Chlorine; Cl2 + CH2=CH2 = CH2Cl-CH2Cl
3. Add Sodium or potassium hydroxide in excess, to 1,2-ddichloroethane; 2KOH + CH2Cl-CH2Cl = CH2OH-CH2OH + 2KCl
2. Add Chlorine; Cl2 + CH2=CH2 = CH2Cl-CH2Cl
3. Add Sodium or potassium hydroxide in excess, to 1,2-ddichloroethane; 2KOH + CH2Cl-CH2Cl = CH2OH-CH2OH + 2KCl
