Resonance Structures

Does the resonance structure matter whether or not an atom is a lewis base or acid?

A Lewis Base is an electron pair donor, and a Lewis Acid is an electron pair acceptor. This classification of acid or base is not determined by a resonance structure of a molecule, but rather is based upon atoms compose the molecule, cation, or anion, and their likelihood to keep or donate electrons. Cations and compounds containing cations, are Lewis Acids because they can accept elections, while anions, or molecules with full octets tend to be Lewis Bases because they can donate elections in a reaction.

The resonance structure does not matter. You can classify an acid by if it accepts electrons, but if it donates electrons then the molecule is a base.

I don't believe that resonance structures should matter when determining if it is an acid or a base.

If the acidic structure has resonance that means that it is usually stronger because it is able to find the most stable form of that molecule due to delocalization and readily give off H+.
