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
