In the 1920s, Gilbert Lewis proposed a new set of definitions for acids and bases.
Understanding Lewis Acids and Bases
Concept #1: Lewis Acids and Bases are defined by their acceptance or donation of an electron lone pair.
Concept #2: Donating an electron lone pair requires the whole molecule to come along.
Example #1: Identify each of the following as Lewis acid or base, Bronsted-Lowry acid or base, or both.
a) Co2+ ____________ c) CH3CONH2 ____________
b) HNO3 ____________ d) CO32- ____________
