Сцепочкой: ch4-ch3oh-ch3cl-c2h4-c2h5cl написать уравнения и название получившиеся веществ.

CH4 + [O] = CH3OH

CH3OH + HCl = CH3Cl + H2O

2CH3Cl + 2Na = C2H6 + 2NaCl

C2H6 =(Ni, p, T) C2H4 + H2

CH2=CH2 + HCl = CH3CH2Cl

 CH4-CH3OH-CH3Cl-C2H4-C2H5Cl

1.две стадии : 

CH4 + Cl2 = CH3Cl + HCl 
CH3Cl + NaOH =CH3OH + NaCl 

2.CH3OH+HCl = CH3Cl +H2O

И снов две стадии : 

2CH3Cl + 2Na = C2H6 + 2NaCl 
C2H6 = C2H4 + H2

C2H4 + HCl =  С2H5Cl
