Homework 3.71

Postby Anna Lapuos 3C » Sun Oct 29, 2017 11:45 pm

How do we know which structure would more likely make the dominant contribution to a resonance hybrid? Does it have to do with the structure with the lower energy?

In such cases you would try to find which structure has a formal charge closest to zero, indicating a more stable molecule (0 being the most stable).

Remember to use the equation, Fc = V - (L + s/2), where V = the number of valence electrons, L = the number of lone electrons, s= the number of shared electrons to calculate the formal charge of each atom in the molecule!!

Also, yes, the most dominant and stable resonance structure will be the one with the lowest energy, which means that it will have a formal charge closest to 0...
