Lewis vs Bronsted

[Yazmin Bocanegra 3L]

How can you tell the difference between Lewis acids/bases and Bronsted acids/bases?

[Madeline Phan 1E]

Lewis acids and bases focus on electron pairs. A Lewis acid is an electron pair acceptor and a Lewis electron pair donor. Bronsted focuses on protons. A bronsted acid is a proton donor and a Bronsted base is a proton acceptor.

[Adrianh72]

Lewis acids and bases deal with what electrons do while Bronsted acids and bases deal with the protons.

[Sanjana Borle 2K]

The general trend is that acids like to become more negative and bases like to become more positive. Therefore, an acid in the Lewis definition is an electron pair acceptor and in a Bronsted definition a proton donor, and a base in the Lewis definition is an e- pair donor and a proton acceptor in the Bronsted definition.
