Stability

Why do resonance structures form a more stable molecule?

Because electrons are delocalized (meaning they are not bound to just one location, for example, a double bond), this makes the molecule more stable. Resonance structures allow for different bond configurations between atoms in a molecule.

The electrons have "different options" in terms of bonds, which means the molecule is less reactive (since there could be higher electron repulsion from electrons being limited to one state).

I hope this makes sense, I'm not entirely sure if the last part is technically right.

Resonance structures are more stable because of the delocalization. Hope this helps!

I think Gabby's explanation is very accurate. Essentially, electrons have to find the most stable position so that they do not interact with other atoms.

They are more stable due to the delocalization of electrons. The energy of delocalized electrons is spread out over a larger area, making it more stable.

Resonance structures are considered to be more stable due to how they allow for the delocalization of electrons, i.e. the jumping of electrons from bond to bond. This "spreading out" of electrons throughout a molecule brings its total energy down, hence making it considerably more stable than other structures where electrons are typically fixed. The big idea of resonance is that the resonance hybrid's structure typically brings the molecule's final energy lower, making it more stable, and thus is the most preferential state.

Resonance structures tend to be stable when there aren't that many charges around it, the shape is in a way balanced, and the pull of bonding atoms canceling out.

Delocalized electrons lower the overall energy of the molecule in a resonance structure making it more stable

Resonance structures are determined to be more stable because they represent delocalized electrons and the fact that they can be found in multiple places. In general delocalized electrons are spread out over the molecule which makes it more stable than if it was fixed location.

Resonance structures form a more stable structure due to delocalization.

Delocalization means that not all the electrons are on one atom but is relatively share amongst them all. So instead of one side being more electron dense, the electron is shared among all areas so make the molecule much for stable and equal (in a way).

They are most stable because the negatively charged electrons are more spread out. In other words because resonance allows for delocalization, in which the overall energy of a molecule is lowered since its electrons occupy a greater volume, molecules that experience resonance are more stable than those that do not.

They are more stable due to the delocalization of the electrons in resonance structures. The electrons have more options and therefore increased stability. I hope this helps!
