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

Re: Delocalization
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.

Re: Delocalization
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.
