Acetic acid cannot be obtained by: a) oxidation of acetaldehyde b) reduction of ethanal c) oxidation of butane d) oxidation of methane
In order to determine which of these options suits us according to the condition, we will write down the reactions:
A) oxidation of acetaldehyde (acetaldehyde) CH3-CH = O + O2 = CH3COOH + H2O;
B) reduction of ethanal (acetaldehyde) CH3-CH = O + H2 = CH3-CH2OH;
C) oxidation of butane (in the presence of a catalyst, at t) 2C4H10 + O2 = 4CH3COOH + 2H2O;
D) methane oxidation CH4 + 2O2 = CO2 + 2H2O.
We see that of the 4 options, A and B are suitable for us.
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.
