Defining Resonance Structures

Postby JamieVu_2C » Sun Nov 03, 2019 1:25 am

Are resonance structures only the Lewis structures by which you can move the double triple bonds? Or do they include all the structures that you can draw for a molecule? For example, with N2O, you can draw different structures with single, double, or triple bonds, so would all those structures be considered resonance? Or is it only when you move the bonds are they then referred to as resonance structures?

Resonance is when there are multiple correct ways to draw the Lewis Structure for a molecule because the bonds are movable and stable in either position, either from rotating the molecule or just simply changing the bonds around for usually every other bond pair. An example of this can be the ion Nitrate NO3- which has multiple ways of drawing its Lewis Structure but it simply moves the double bond pair to different locations

Resonance structures I believe only apply to when there are multiple ways of drawing the exact same structure. For example, moving the location of a double bond would make another resonance structure.

I think that formal charge also comes into play.
