1) 2CH₃Cl + 2Na = C₂H₆ + 2NaCl
2) C₂H₆ =(Ni,p,t°)= CH₂=CH₂ + H₂
3) CH₂=CH₂ + H₂O = CH₃CH₂OH
4) 2CH₃CH₂OH + 2Na = 2CH₃CH₂ONa + H₂
2 цепочка:
1) CaC2 + 2 H2O = Ca(OH)2 + C2H2
2) C2H2 + H2 = C2H4
3) C2H4 + H2 = C2H6
4) C2H6 + Cl2 =(уф)= C2H5Cl + HCl
5) C2H5Cl + NaOH(водный раствор) = C2H5OH + NaCl
3 цепочка:
1) 2CH4 =(1500°)= C2H2 + 3H2
2) 3C2H2 =(Cакт., 500°C)= C6H6
3) C6H6 + Cl2 =(Fe³⁺)= C6H5Cl + HCl
4) C6H5Cl + NaOH = C6H5OH + NaCl
