Acetic acid cannot be obtained by: a) oxidation of acetaldehyde b) reduction of ethanal

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.
