1) 2H3CCOONa + 2H2O (электролиз) = C2H6 (X) + 2NaHCO3 + H2;
2) C2H6 + Cl2 (+hv) = H3C-CH2-Cl + HCl;
3) H3C-CH2-Cl + C2H5OK = H2C=CH2 (Y) + C2H5OH + KCl;
4) H2C=CH2 + H2O (+H2SO4) = H3C-CH2-OH;
5) 2H3C-CH2-OH (+T, Al2O3) = H2C=CH-CH=CH2 + H2 + 2H2O;
6) n H2C=CH-CH=CH2 (R-O-O-R) = [-H2C-CH=CH-CH2-]n.
