Delocalization

Postby Camellia Liu 1J » Fri Oct 25, 2019 11:12 am

What does it mean when an electron is delocalized and how do you know when it is delocalized? What are the implications in double and triple bonds?

Electrons are delocalized when there is resonance in the structure of the molecule. Delocalization means the electron isn't bound to stay in one subshell, instead it can "move around" from subshell to subshell per se. That is why we draw all the possible structures when we draw resonance because the electrons are delocalized there.

Like the previous poster said, delocalization is when there is resonance in the structure of the molecule. You know an electron is delocalized when it is possible for structures to have multiple bonds in different locations (ex. NO3 example from class; the double bond with nitrogen and oxygen can be at any three of the oxygens in the molecule). In reality, the real structure is a blend of all possible structures.
