Delocalized Pi Bonding

Postby Meigan Wu 2E » Wed Nov 28, 2018 10:17 pm

Can someone explain what delocalized pi bonding is and when does it exist?

Delocalized pi bonding is essentially the sharing of a pi bond over more than two nuclei. This can be prominently be seen with benzene, which shares 3 pi bonds over 6 carbon nuclei and contributes to the ring of electron cloud density characteristic of benzene.

this is the cloud of electrons over a molecule it an have three pi bonds on every other bond, and due to resonance there are characteristics of double bonding at every bond at the same time, resulting in a delocalized pi bond over the entire molecule.

A delocalized pi bond is when electrons can freely move more that two nuclei. You will often see this in a lewis structure in carbon rings. Carbon rings often consist of double bonds. These pi bonds that are spread out over the lewis structure means the pi bonds are delocalized as they do not reside in only one area.
