lewis vs. bronsted

[Aashka Popat 1A]

What is the distinction between a Lewis acid/base and a Bronsted acid/base? Why are they interchangeable?

[Johnathan Smith 1D]

Bronsted acids donate electrons and Lewis acids accept electrons

[505316964]

A Bronsted Acid is a proton donor, a Lewis Acid accepts an electron pair. These are interchangeable because they are saying the same thing. When a proton is donated, the molecule becomes more negative, which is like accepting an electron pair. Bronsted and Lewis acids are the same thing, just a different way of describing what they do.

[Nick Lewis 4F]

Is donating a proton really the same as accepting an electron pair? What is the distinction and when does it come into play or are they exactly the same thing just interchangeable terms?

[Serena Siddiq 3D]

This is incorrect, Bronsted Acids donate PROTONS not electrons.

Bronsted acids donate electrons and Lewis acids accept electrons

A Bronsted acid is a proton donor while a Lewis acid accepts an electron pair.

[Tahlia Mullins]

Bronsted acids donate protons whereas Lewis acids take in protons, or rather, accept them. Do not confuse protons with electrons here!

[Johnathan Smith 1D]

Sorry that was my bad. I thought I had put down protons. Thanks for correcting it!

Do we need to know about the Arrhenius acids and bases? I saw it in the textbook but I do not remember him mentioning it in class.

[Cynthia Rodas 4H]

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

Thank you so much this helps a lot.
