Best Resonance Structure

Postby vanessas0123 » Fri Nov 15, 2019 4:07 pm

Why's the best / most stable resonance structure the one with the least formal charge?

The best resonance structure has a formal charge closest to 0 because it means that the atom has the best balance of bonds to lone pairs according to its valence, meaning that it is stable.

All the resonance structures should have the same charge because the only thing that is changing is the placement of the bonds.

The best resonance structure is when the central atom has a formal charge closest to 0, that is when the structure is most stable.

The goal is always to make the charge of each atom in the Lewis Structure to be closest to 0, so the best resonance structure is when the atoms are closest to 0 but if that's not possible just try to get the central atom to 0

Since the formal charge can be negative or positive, the lower the formal charge, the higher the stability.
