Bond Lengths

Postby salvadorramos3k » Wed Dec 04, 2019 3:12 am

How come delocalized electrons still allow for bond lengths to be the same even though double bonds are technically shorter than single bonds.

Delocalized electrons are associated with resonance structures. If a molecule has resonance, the molecule is like a "blend" of all the resonance structures combined. Therefore, the bond lengths that participate in the resonance would all be a "blend" of each other and be the same length.
