Most stable lewis

Postby Diego Gonzalez 3F » Wed Oct 31, 2018 7:35 pm

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

All resonance structures by definition are equally likely to occur, so they're all equally stable. To decide what Lewis structure in general is the most stable for a molecule, use the formal charges. The Lewis structure with the most formal charges of 0 is the most stable.
