Re: Resonance and bond lengths
Hi! When there's resonance, the electrons are delocalized and spread throughout the entire molecule. This lowers the overall energy of the molecule (the electrons occupy a larger volume), and therefore stabilizes the anion. Hope this helps!
Re: Resonance and bond lengths
Resonance occurs in molecules with double bonds and often when there is a formally negatively charged oxygen. So to use carboxylate ions as an example, you can have the double bond and negative charge in two places once a carboxyl group loses its hydrogen. The negative charge is delocalized because the negative charge is half the time on one oxygen and half the time on the other oxygen, so this is what makes it stable.

Re: Resonance and bond lengths
Electrons are delocalized in resonance structures so they are spread out and occupy a larger volume. This means that there is less electron repulsion, causing the structure to be more stable.

Re: Resonance and bond lengths
Electrons are delocalized in resonance, which results in a lower overall energy which stabilizes the anion.

Re: Resonance and bond lengths
When an atom has resonance structure, negative formal charges on certain atoms will be spread out ("delocalized") around all atoms. This lowers total energy of the molecule, making the molecule more stable.

Hello!
Yes, an anion can be stabilized by resonance. This is because resonance allows the electrons to be spread through the molecules, lowering the overall energy and lessening electron repulsion. Hope this helps!
