Resonance

[Frederick Keith_4C]

Resonance is when some Lewis structures have multiple bonds with the same chemical connectivity but the electrons are distributed differently around the structure. So my question is what does it say about a molecule or compound if it can form multiple different resonant structures???
For example, if a molecule has 2 different structures how does it compare to a molecule that can form maybe 4 different structures?

[Kimberly Koo 2I]

Molecules that have resonance are known to be more stable since the double bonds can be placed in more different positions. So a molecule that can form 2 different structures is less stable than a molecule that can form 4 different structures, but is more stable than a molecule that doesn't have resonance
