Bronsted Acids & Bases vs. Lewis Acid & Bases

Postby 705170809 » Sun Nov 18, 2018 8:10 pm

What's the different between Bronsted and Lewis acids and bases? I know that acids are electron acceptors, while bases are electron donors, however I don't know the different between the two labels of acids and bases.

There might be a few other differences but the rule for Bronsted is that an acid is a proton (H+ ion) donor, and a base is a proton acceptor. And the rule for Lewis bases is that an acid is an electron acceptor, and a base is an electron donor.

Lewis acids are electron pair acceptors and Lewis bases are electron pair donors.
Bronsted Lowry acids are proton donors and Bronsted Lowry bases are proton acceptors.

A Lewis acid is an electron acceptor, and a Lewis base is an electron donor. On the other hand, a Bronsted acid is a proton donor, and a Bronsted base is a proton acceptor. The definition that you use just depends on whether you're focusing on the transfer of electrons or protons.
