Bond lengths

[Alfred Barrion 2H]

Why is it when there is a resonance structure, all of the bond lengths are the same even though there's double and single bonds.

[Maya Serota 3G]

The structure represents it that way because it is the best we can do, but in reality there aren’t actually double and single bonds like that.

[Aadil Rehan 1D]

Resonant compounds have more delocalized electrons, so they're kind of swooshing around the bonds all the time. The bond length we have is an average of what is measured.

[EricZhao3G]

In reality, the molecule is a resonance hybrid and is a combination of all of the resonance structures. This results in a bond length between a single and double bond since the bonds are defined as neither a single bond nor a double bond.

[Lauren Tanaka 1A]

All the bond lengths are the same because in resonance structures the bond lengths are an average of every single bond leading them to all be the same length.

[Joanne Lee 1J]

The bond lengths are the same value because the actual structure is a mixture of all the different versions of the resonance structure. Therefore, it isn't just one that has a double bond and the rest a single bond but all the bonds are a mixture of both, making the bond length in between the value of a double and single bond.

[Jainam Shah 4I]

The electrons that are shared are delocalized meaning a specific single or double bond doesn't have full control of them. They are delocalized and the effect is spread among the entire structure. So a single bond has some double bond character while a double bond has single bond character. This is why all bonds are an intermediate length between the length of the single and double bond.

[emma brinton_3B]

this is because the actual structure of the molecule is a hybrid of the resonance structures, meaning the bond lengths would be an average of each other.

[Giselle Littleton 1F]

The bond lengths are all the same in the resonance structure because the structures all approximate the actual structure that is supposed to form. That is, the resonance structures are a mix of structures close to the actual structure.

[Astrid Lunde 1I]

The bond lengths are all the same because the actual structure is a mix of all the resonance structures.

[Kishan Shah 2G]

This is due to the fact that the electrons are delocalized. Therefore, the bonds in the structure are a blend of single and double bonds, or in another words they have single and double bond character. Therefore the bond lengths are the same.
