Most stable lewis
How do we know which resonance structure is the most stable? Can you do it by just looking at the lewis structures?

Re: Most stable lewis
In order to know the most stable lewis structure, you should calculate the formal charge. The most stable lewis structure has the least formal charge on each atom.

Re: Most stable lewis
The most stable Lewis structure is determined by finding a structure that has the least formal charge on each atom. In order to find the formal charge of an atom, you use this formula: Formal Charge = [# of valence electrons on atom] – [non-bonded electrons + number of bonds]
Re: Most stable lewis
Formal charge is used to determine the stability of a molecule. However, resonance structures, since they are different arrangements of the same bonds, are equally stable as one another.
