Lewis vs. Bronsted

[Lizbeth Crisanto 3D]

What is the difference between Lewis acids and bases and Bronsted acids and bases?

[Alex FreeWolf 2E]

A Bronsted Acid is defined as a proton donor

A Lewis Acid is defined as an e pair acceptor.

Bronsted Acids usually must contain hydrogen to be classified as such. It’s just a different way of defining the same thing (an acid)

[Monse Mata 3D]

Lewis definition of an acid: e- pair acceptor
Lewis definition of a base: e- pair donor
Bronsted Lowry definition of an acid: proton donor
Bronsted Lowry definition of a base: proton acceptor

I hope this helps! :)

The Lewis definition of an acid/base focuses on what happens with electron pairs. A Lewis acid accepts a pair of electrons and a Lewis base donates a pair of electrons. The Bronsted definition of an acid/base focuses on what happens with protons. A Bronsted acid donates a proton and a Bronsted base accepts a proton.

To be simple, relationship with electrons vs protons.

[Arad_Badiee_2B]

Broasted-Lowry acids are H+ donors. Lewis acids are e- acceptors and visa versa.

[Dillon Taing 3H]

Lewis acids/bases are defined by what happens to a pair of electrons. Bronsted Lowry acids/bases are defined by the transfer of protons.

[Alekhya_Pantula_2E]

Lewis acids and bases and Bronsted kind of work like opposites. Lewis bases are the electron donor, while Bronsted bases are proton acceptor. Similarly, Lewis acids are electron acceptors while Bronsted acids are proton donators.

Hi!

Lewis acids accept electron pairs and Lewis bases donate electron pairs. Bronsted acids donate protons and Bronsted bases accept protons. Hope this helps.

[Akshat Katoch 2K]

Lewis acids are e- pair acceptors.
Lewis bases are e- pair donors.

Bronsted acids are proton (H+) donors.
Bronsted bases are proton accepts.

Another way to think about this is that in a Lewis acid the proton is an acid (Accepts e-), but a Bronsted acid is the species that supply the proton However, for both whoever accepts the proton is the base.
