Fixed. Thank you.

In many books the pKa of water is listed as 15.7. However there seem to be several errors in how this number was arrived at. I have corrected earlier versions of this post which had that value and replaced them with a value of 14, so no, methanol is not a stronger acid than water.

I fixed the typo with respect to the favorability of the acid-base reaction. Thanks.

Corrected this typo. Thanks for letting me know!

This was a mistake. Fixed. Thanks!

This has been fixed. Thank you for bringing it to my attention!

Because of this I am not able to properly grasp what is given in the second point can you please explain.

Shouldn’t the equilibrium favor methanol??

In the graphic showing a Claisen condensation reaction, isn’t the final product CH3OH, rather than CH3O? Else, where has the H gone? Maybe I missed something..

Thanks
