Re: Ester Naming Conventions

If you make an ester from ethanoic acid and propanol, you get ethyl propanoate. No, that would be from ethanol and propanoic acid, since the -ate is always from the acid just as if you were naming a salt. So your combination would give you propyl ethanoate (or propyl acetate), and likewise propan-2...
