Ацетилен-этилен-этанол-хлорэтан-бутан

1) C2H2 + H2 -Ni,t-> CH2=CH2
2) CH2=CH2 + H2O -H2SO4,t> CH3-CH2OH
3) CH3-CH2OH + HCl -> CH3-CH2Cl + H2O
4) 2CH3-CH2Cl + 2Na -> CH3-(CH2)2-CH3 + 2NaCl

1)С2Н2 + H2=C2H4
2)C2H4 + H2O = C2H5OH
3)С2H5OH + HCl → C2Н5Cl + H2O
4)C2H5Cl + H2O —> C2H5OH + HCl
5)2 CH3CH2OH → CH3CH2OCH2CH3 + H2O
