bond length

[aaronharouni]

How are bond lengths the same if there are two double bonds and one single bond? Is it bc of resonance?

[Francis_Nguyen3D]

Bond lengths could be the same because of resonance. Resonance molecules do not have one true lewis structure, but rather a variety of structures. Because of this, the resonance lewis structure of a given molecule would be a hybrid of all the possible structures that could be created. This would make bond lengths the same even if they are double and single bonds.

[Tony Chung 2I]

It is because of resonance. Resonance tells us that there is more than one lewis structure for a specific compound.

[Hailey Boehm 2H]

Yes, it is because of resonance. Electrons are delocalized in resonance structures. For example, Benzene, C6H6 has 3 delocalized double bonds. Lewis structures therefore place limitations on depicting the true e- placement in resonance structures, because they prevent us from depicting the blending of structures.

The bond lengths are still the same probably because of resonance. All bond lengths are the same even though they are single or double because resonances are hybrids

How would you find the bond length in a resonance structure? Would it just be the average of the different length bonds?
