Lewis Acid/ Base Notes

Review What is the Arrhenius definition of an acid and base? Acid - Substance that when dissolved in water, will yield H+ ions Substance that yields hydroxide ions (OH-) as the only negative ions in an aqueous solution What is the Bronsted-Lowry definition of an acid and base? An acid is a substance that can donate a proton Any substance that can combine with or accept a proton (H+)

Lewis Acid/ Base (Definition 3) Lewis Acid – a substance that can accept a pair of nonbonding electrons (H+) Electron-pair acceptor Lewis Base – a substance that can donate a nonbonding pair of electrons (OH-) Electron-pair donator
