Hi,

I am looking for any ideas that could explain why is mobile phase containing methanol better in resolution of enantiomers than ethanol or any other organic solvents.

Thaks, M.
I would guess the 2 pairs of electrons on the Oxygen have something to do with this. But Oxygen also comprises Ethanol, Propanol, Butanol...

Actually, I would not expect that to be generally true, or are you talking about a specific case?
