CaCO3 + 4C = CaC2 + 3CO

CaC2 + 2H2O = C2H2 + Ca(OH)2

C2H2 + H2 = C2H4

C2H4 + HCl = C2H5Cl

C2H2 + HCl = C2H3Cl

C2H5Cl+C2H3Cl + 2Na= CH3-CH2-CH=CH2 + 2NaCl

CH3-CH2-CH=CH2 + HBr (H2O2) = CH3-CH2-CH2-CH2Br

CH3-CH2-CH2-CH2Br + KOH(H2O) = CH3-CH2-CH2-CH2OH + KBr

CH3-CH2-CH2-CH2OH + CuO = CH3-CH2-CH2-COH + Cu + H2O

CH3-CH2-CH2-COH + [O} = CH3-CH2-CH2-COOH

В последней реакции - CH3-CH2-CH2-COH + KMnO4 + H2SO4
