1) алкан-галогенопроизводное

C2H6 + Cl2 = C2H5Cl + HCl

2) С2H5Cl + KOH = C2H4 + KCl + H2O

3)C2H4 + H2O = C2H5OH

4)C2H5OH + CH3COOH = CH3 - COO-C2H5 + H2O

5)CH3 - COO - C2H5 + KOH = CH3COOK + C2H5OH

1) СaC2 + 2H2O = Ca(OH)2 + C2H2

                              Hg(2+)

2)C2H2 + H2O CH3COH

                                       t,аммиачный раствор

3)CH3COH + Ag2O    CH3COOH   + 2Ag

                                                                 O

                                                               //

4)CH3COOH + C2H5OH = CH3 - C                        + H2O

                                                               \

                                                               O - C2H5

5)            O
