Bronsted vs Lewis

Postby Chris Dis3L » Sun Dec 02, 2018 11:59 pm

Which is the more accurate way to identify a molecule as an acid or a base? Does the Bronsted definition encompass a wider range or application or does the Lewis definition? Are both definitions needed to properly perform experiments with acids and bases?

I think in class it was stated that either definition will work for this class, and both sufficiently cover what we need to know.

The Lewis definition is more broad then the Bronsted definition. For example, BF3 is a Lewis acid because it accepts an electron pair from F- to form BF4-. However, it would not be classified as a Bronsted acid since it does not donate a proton.
