Delocalized π bonds

Postby Jalaia Jackson 2G » Sun Nov 29, 2020 12:03 am

So in terms of Lewis structures, delocalized π bonds can only occur with resonance structures, or even if a molecule doesn't have a resonance structure can delocalized π bonds exist? I'm referring to the solution of question 16 on Sapling just for clarification.

I believe resonance would be the only way delocalized pi bonds exist as resonance describes the delocalization of electrons.

Resonance is the only way in which delocalized pi bonds can occur because the different structures implies different electron placements.

I think that delocalized pi bonds only exist in the abstract and the term doesn't refer to an actual formation of electrons.

Delocalized pi bonds refer to those in which electrons can freely move between atoms, mainly referring to the bonds within resonant molecules. This is because the pi bond(s) is constantly moving throughout the molecule, hence they are "delocalized".

Delocalized pi bonds can only exist in a resonance structure. Since pi bonds typically exist in double or triple bonds, that double/ triple bond is able to move around in a resonance structure, meaning the pi bond is moving with it too. Therefore, the electrons for the pi bond are never permanently in place as they move with the bonds in a resonance structure, so they are considered delocalized.

What is a pi orbital?
