Let’s solve the chain of transformations:
1.C2H6 – C2H4 – C2H4O – CH3 – CHO – (CH3COO) 2Ca.
2. We compose equations for organic substances:
C2H6 = H2 + H2C = CH2 – dehydrogenation, ethylene obtained;
H2C = CH2 + H2O = CH3 – CH2 – OH – hydration, ethanol is released;
CH3 – CH2 – OH + CuO = CH3 – COH + Cu + H2O – oxidation with copper oxide, ethanal is formed;
CH3 – COH + Ag2O = CH3 – COOH + 2Ag – silver mirror, ethanic acid, silver are released;
2СН3СООН + Ca = (CH3COO) 2Ca + H2 – substitutions, calcium acetate was obtained.
The processes confirm the connection of hydrocarbons with oxygen-containing organic substances.
