lewis vs bronsted

[Hannah Kaye 1L]

Hi, I am confused on the differences between bronsted and lewis acids and bases?

[Jessica Tam 3H]

Hi,
The Bronsted definition classifies acids as the ones that are the proton donors, and the bases as the proton acceptors. Lewis acids are the electron acceptors and bases are electron donors.

Bronsted acids can donate a proton, while bronsted bases can accept a proton. On the other hand, Lewis acids can accept electrons while lewis bases can donate electrons.

Bronsted and Lewis are the two different interpretations of acids and bases. With Bronsted, an acid is an H+ donor and a base is an H+ acceptor, and with Lewis an acid is an electron acceptor and a base is an electron donor. Both definitions are essentially saying the same thing as far as charge goes, but are different in terms of what is causing this change in charge.

Hi,
A bronsted acid is a proton (H+) donor. A bronsted base is a proton (H+) acceptor.
A Lewis acid is a lone pair acceptor while a Lewis base is a lone pair donor. Hope this helps!
