Determine substance x in the scheme CH4 – X – CH3CHO

Let’s write down the chain of transformations for organic substances:
CH4 – C2H2 – CH3CHO;
Let’s implement the solution:
2CH4 = C2H2 + 3H2 – decomposition of methane, occurs when heated, acetylene is released;
C2H2 + H2O = H2C = CH2OH (vinyl alcohol) – hydration of acetylene, vinyl alcohol is formed – an unstable compound;
Н2С = СН2 – ОН = СН3 – СНО – isomerization, acetaldehyde obtained.
These reactions confirm the connection between alkanes, alkynes, aldehydes. The final product, acetaldehyde (ethanal), is used to obtain acetic (ethanic acid).
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
