1) СН3-СН3 + Cl2   =>    C2H5Cl + HCl

2) C2H5Cl + NaOH(водный раствор)    =>   C2H5OH + NaCl

3) CH3-CH2-OH + CuO   =>   CH3-CHO + Cu + H2O

4) CH3-CHO + 2Cu(OH)2 (нагревание)   =>  CH3-COOH + Cu2O + 2H2O

5) CH3COOH+Cl2    =>   CH2ClCOOH + HCl

6) CH2ClCOOH + 2NH3    =>  NH2CH2COOH + NH4Cl

7) 2NH2CH2COOH + 2Na  =>   2NH2CH2COONa + H2
