# Does the oxidation for all the aliphatic monoaldehydes to carboxylic acids have the same value of electrode potential?

I have been wondering on this for quite a while. Consider aliphatic monoaldehydes. If I oxidize them, we get corresponding monocarboxylic acids. We can use certain oxidizing agents to perform the reaction.

For all the possible aliphatic aldehydes, it involves breaking a $\ce{C-H}$, and the formation of the $\ce{C-O}$ and a $\ce{O-H}$. I did calculations and got the enthalpy change for such a process to be $\pu{412kJ/mol}$.

My main motive is to find the electrode potential for the process. Unfortunately, I cannot determine the entropy here, although I don't think the side chain would matter much.

Here's my question. Does the oxidation for all the aliphatic monoaldehydes to carboxylic acids have the same value of electrode potential? In all the cases, it's the same bonds broken and same bonds formed, so I cannot see why the electrode potential should drastically vary for different aldehydes.

My apologies, I was unable to find a $\Delta\text{G}$ value table for such processes.
