1) CH3-CH2-CHCl2 + 2KOH --> CH3-CH2-CH(OH)2 + 2KCl

2) 4CH3-CH2-CH(OH)2 + K2Cr2O7 + 3H2SO4 --> 4CH3-CH2-COOH + K2SO4 + 2CrSO4 + 7H2O

3) CH3-CH2-COOH + Cl2 --> CH3-CHCl-COOH + HCl

4) CH3-CHCl-COOH + NaHCO3 --> CH3-CHCl-COONa + CO2 + H2O

5) CH3-CHCl-COONa + CH3-CH2-Br --> CH3-CHCl-COO-CH2-CH3 + NaBr
