Помогите с преобразованием. CH4---C3H6--C3H4--C3H8O--CO2

1) CH4 + Cl2 - > CH3Cl + HCl

CH3Cl + Na - > C2H6 + NaCl

C2H6 + Cl2 - > C2H5Cl + HCl

C2H5Cl + CH3Cl + Na - > C3H8 + C2H6 + C4H10 + NACl

C3H8 + Cl2 - > CH3-CHCl-CH3 + HCl

CH3-CHCl-CH3 + KOH - > CH2=CH-CH3 (C3H6) + KCl + H2O

2) CH2=CH-CH3 + HCl - > CH3-CHCl-CH3

CH3-CHBr-CH3 + Cl2 - > CH2Cl-CHCl-CH3 + CH3-CCl2-CH3

CH2Cl-CHCl-CH3 + 2KOH - > C3H4 + 2KCl2 + 2H2O

и так далее)
