А) С2H4 -> C2H2 + H2
3C2H2 -> C6H6
C6H6 + Cl2 [FeCl3] -> C6H5Cl + HCl
C6H5Cl + NaOH -> C6H5OH + NaCl
Б)СH4 + Cl2 --(hv)--> CH3Cl + HCl
CH3Cl + NaOH --(H2O, t)--> CH3OH + NaCl
CH3OH + CuO --(t0)--> CH2=O + Cu + H2O
CH2=O +H2 --(Ni)--> CH3OH
В)СH3-CH3 + Cl2 = CH3-CH2Cl + HCl
CH3-CH2Cl + NaOH(водн. р-р) = CH3-CH2OH + NaCl
CH3-CH2OH + O2 = CH3COOH + H2O
CH3COOH + KOH = CH3COOK + H2O
