1)C3H6СL2+KOH=X   2)X + K2Cr2O7 + H2SO4=CH3CH2COOH   3)CH3CH2COOH + Cl2= X2    4)X2 +NaHCO3= X3    5)X3 + CH3CH2Br=X4

Answer 1

1)C3H6CI2 + 2KOH = C3H6(OH)2 + 2KCI;

2)4C3H6(OH)2 + K2Cr2O7 + 3H2SO4 = 4CH3-CH2-COOH + K2SO4 + 2CrSO4 + 7H2O;

3)CH3-CH2-COOH + CI2 = CH3-CHCI-COOH + HCI;

4)CH-CHCI-COOH + NaHCO3 = CH3-CHCI-COONa + CO2 + H2O;

5)CH3-CHCI-COONa + CH3-CH2-Br = CH3-CHCI-COO-CH2-CH3 + NaBr.
