1)CH3-CH3 ->(t°,Ni) CH≡CH + 2H2
2)CH≡CH + 2H2 ->(t°,Ni) CH3-CH3
3)CH≡CH+H2O -> (Hg²+;t°) ->CH3-CHO
4)CH3-CHO + 2Cu(OH)2 ->(t°) CH3-COOH + Cu2O + 2H2O
5) CH3-COOH + CH3OH ⇄ (H+;t°) CH3-COO-CH3 + H2O
6)CH3-COO-CH3 + H2O ⇄(H+;t°) CH3OH + CH3-COOH
7)CH3-COO-CH3 + H2O ⇄(H+;t°) CH3OH + CH3-COOH
8)CH3-COOH + CH3OH ⇄ (H+;t°) CH3-COO-CH3 + H2O
9) CH3-CHO + H2 -> (t°;Ni) CH3-CH2OH
10)CH3-CH2OH + CuO -> (t°) CH3-CHO + Cu + H20
11)CH3-CH2OH + HCL -> CH3-CH2Cl + H2O
