Write the reaction equations: CH4 → C2H2 → CH3COH → CH3COOH → (CH3COO) 2Mg

Let’s execute the solution:

Methane – ethine – acetaldehyde – acetic acid – magnesium acetate
We compose the equations of processes for organic substances:
2CH4 = C2H2 + 3H2 – decomposition or thermal cracking is carried out at a temperature of 500 degrees, ethine is obtained;

С2Н2 + Н2О = Н2С = СНОН = СН3 – СОН – hydration of ethine, an intermediate product of vinyl alcohol is formed, after the process of its isomerization, acetaldehyde is released;

CH3 – СОН + Ag2O = CH3COOH + 2Ag – a qualitative reaction to aldehyde occurs when the ammonia solution is heated and silver oxide participates, acetic acid is obtained;

2СН3СООН + Mg = (CH3COO) 2Mg + H2 – substitutions, magnesium acetate is released.

The solution process showed the connection between hydrocarbons and oxygen-containing organic substances. The reaction products are of practical importance, for example, acetic acid is used in organic synthesis as an oxidizing agent.
