Lewis Acids & Bases vs Bronsted Acids & Bases

Postby Nikhita_Jaaswal_2H » Sun Nov 20, 2016 8:34 pm

Hi,

I was wondering if someone could please explain to me the difference between a Lewis Acid/Base as compared to a Bronsted Acid/Base?

Lewis Acid/Base:
An acid accepts electrons, a base donates an electron.

Bronsted Acid/Base:
An acid donates a proton (H+ ion), a base accepts a proton.

I'm familiar with these definitions, and I hope this helps. I know that it's possible for a reaction to be a Lewis acid/base reaction and not a Bronsted reaction - so perhaps that's the significance in the distinction between the two.

A tip I had when memorizing these
Their roles kinda flip (acid from acceptor to doner, and vice versa for base), which make sense, as protons and electrons are the opposite (strictly charge speaking) of each other
