Напишите уравнения реакций С3H7COONa → X1 → X2 → X3 → X4 → CH4

1) С3H7COONa + NaOH(тв.) →C3H8↑ + Na2CO3
2) CH3-CH2-CH3 +Cl2 → CH3-CHCl -CH3 + HCl
3) CH3-CHCl -CH3 + NaOH → CH2=CH-CH3 + NaCl
4) CH2=CH-CH3 + 2KMnO4 + 3H2SO4 → CH3COOH + CO2 + 2MnSO4 + K2SO4 + 4H2O
5) CH3COOH + 2NaOH((тв. изб.) → CH4↑ + Na2CO3
