А) С + 2Н2 = СН4
   СН4 + Cl2 = CH3Cl + HCl
   2CH3Cl + 2Na = C2H6 + 2NaCl
   2C2H6 + 7 O2 = 4CO2 + 6H2O

б) C2H6 + Br2 = C2H5Br + HBr
   2C2H5Br + 2Na = C4H10 + 2NaCl
CH3-CH2-CH2-CH3 ===AlCl3==== CH3-CH-CH3
                                                            I
                                                            CH3
2C4H10 + 13 O2 = 8CO2 + 10H2O
