Question

                                                                                                   этаналь → ацетат калия → СН4(1500) → X1 → K2C2O4 ( H2SO4, конц.t  )  → X2

Answer 1

1) 3H3C-CHO + 2KMnO4 = 2H3C-COOK + H3C-COOH + 2MnO2 + H2O;

2) H3C-COOK + KOH (сплав.) = CH4 + K2CO3;

3) 2CH4 (1500 C) = C2H2 (X1) + 3H2;

4) 3C2H2 + 8KMnO4 = 3K2C2O4 + 2KOH + 8MnO2 + 2H2O;

5) K2C2O4 + H2SO4 (конц., при нагр.) = K2SO4 + CO (X2) + CO2 + H2O.
