А) CH₃-CH₃ + Cl₂ ---> CH₃-CH₂Cl + HCl (hv)
CH₃-CH₂Cl ---> CH₂=CH₂ + HCl
CH₂=CH₂ + [O] + H₂O ---> OH-CH₂-CH₂-OH (kt=KMnO₄,t)
б) OH-CH₂-CH₂-OH + 2HCl ---> Cl-CH₂-CH₂-Cl + 2H₂O
Cl-CH₂-CH₂-Cl ----> HC≡CH + 2HCl
HC≡CH + 2H₂ ----> CH₃-CH₃ (Kt=Ni,t)
CH₃-CH₃+ Cl₂ ---> CH₃-CH₂Cl + HCl (hv)
CH₃-CH₂Cl + KOH --> CH₃-CH₂-OH + KCl
CH₃-CH₂-OH ---> CH₂=CH₂ + H₂O (Kt=H₂SO₄,t)
CH₂=CH₂ + [O] + H₂O ---> OH-CH₂-CH₂-OH (kt=KMnO₄,t)
