1. Решите цепочки превращений: 1) C2H6→ C2H5Br → C2H4 → C2H4Cl2

1) С2H6+Br2=C2H5Br+HBrC2H5Br+KOH (спиртовой)=C2H4+KBr+H2OC2H4+Cl2=C2H4Cl22) CH3─CH2─CH2OH- (t больше 140 градусов, H2SO4)=Ch3-CH=Ch2+H2OCh3-CH=Ch2+H2O- (H2SO4) -CH3─CHOH─CH3 3) CH3─CH2─CH2OH — (t больше 140 градусов, H2SO4)=Ch3-CH=Ch2Ch3-CH=Ch2+HCl-Ch3-CH (Cl) -Ch32Ch3-CH (Cl) -Ch3+2Na-H3C-Ch (Ch3) -Ch (Ch3) -Ch3+2NaClH3C-Ch (Ch3) -Ch (Ch3) -Ch3- (t, кат) — H3C-C (Ch3)=C (Ch3) -Ch33H3C-C (Ch3)=C (Ch3) -Ch3+2KMnO4+4H2O-3H3C-C (OH) (Ch3) -C (OH) (Ch3) -Ch3+2KOH+2MnO2
