Resonance with formal charge

Postby ConnorRazmaDis2I » Sun Nov 04, 2018 8:49 pm

If a molecule has a formal charge that favors one form of a Lewis structure over another does the molecule still have resonance?

Yes. Resonance is simply different ways of drawing a molecule's structure in terms of double bonds. Formal charge is the most stable structure of all resonance structures.

Molecules may still have resonance even when the specific molecule is not in its most stable form. Resonance has nothing to do with the stability of the molecule.

The resonance of a structure will not change the FC.

Yes, the molecules can still have resonance as long as the number of electrons still works in the Lewis structure! The lowest formal charge just indicates the stability of the structure.

So formal charge doesn't really have anything to do with resonance?

yes it can still have resonance. The formal charge is used to find the most stable Lewis electron dot structure, ones with elements of formal charge closest to 0.
