The Lewis Acid-Base Definition
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
The Lewis definition names an acid as an electron-pair acceptor and a base as an electron-pair donor, covering reactions with no proton transfer.
Show
Boron trifluoride accepts an electron pair from ammonia's nitrogen, BF3 + NH3 → F3B–NH3, with no proton moving.
Watch for
A reaction with no proton in sight can still be acid-base chemistry under the Lewis definition alone.
