Formal charges on structures

Postby Jamie Lee 1H » Sun Nov 03, 2019 12:00 pm

When creating Lewis structures of lowest energy, do you want the most formal charges to be 0 and if there is a charge forit to be on the element that is the most electronegative?

Yes, the best structures have elements with 0 formal charge. If not, the most electronegative element should carry the negative formal charge.

Yes, the most stable resonance structures or Lewis diagrams in general include as many formal charges of 0 as possible.
