Lewis and Bronsted

Postby Aedra Li 3H » Wed Dec 04, 2019 9:03 pm

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

Lewis acids are more encompassing term while Bronsted is more specific. Bronsted acids are those that donate an H+ or proton in a reaction, while lewis acids are electron acceptors in a reaction. Therefore, every Bronsted acid is a lewis acid but some lewis acids such as Al2O3 are not necessarily Bronsted acids. Hope this helps!

Bronsted bases and acids deal with protons (H+) where bases accept protons while acids give them off. Vice versa with Lewis bases and acids except it would be electrons instead of protons.

In terms of the Lewis definition, the acid is an electron pair acceptor. On the other hand, according to the Bronsted-Lowry definition, the compound that donates a proton is the acid. For both definitions, the base is the compound that accepts a proton.
