Delocalization

Postby Shanzey » Sun Oct 27, 2019 7:55 pm

If a molecule has resonance, does that mean it is delocalized, or does delocalization only occur under specific conditions?

Eelectrons involved in resonance structures are delocalized. Electrons that appear in different positions in a set of resonance structures are said to be delocalized, meaning that a shared electron pair is distributed over several pairs of atoms and cannot be identified with just one pair of atoms.

Delocalization of electrons occurs in resonance structures. This is why, experimentally, all bond lengths are the same even if one of the molecule's bonds is a single and the other a double. The electrons do not stay localized to only one of the bonds, and instead they move around the molecule, causing a blended bond length.

Delocalization will occur in all resonance structures.
