Delocalized Pi bond

[Melody Haratian 2J]

Hi guys!
I’m still a bit confused on this but can someone explain what makes a delocalized pi bond and what makes it different from a regular pi bond?

A delocalized π bond is a bond in which the electrons are free to move to more than one atom. Delocalized pi bonds are seen in resonance structures with different possible locations of double and triple bonds.

A delocalized pi bond is a pi bond in which the electrons are free to move over more than two nuclei. A regular pi bond is a localized pi bond in which the bonded electrons are confined to a concentrated region between two separate atoms.

Delocalized pi bonds occur when pi bonds extend to more than 2 atoms. There is an exercise on Sapling about that.

Yeah I think it is question 16

Hi Melody!

I was also confused on this when I first saw it as well, but after answering the question and reading the solution to it, it became more clear. So when a delocalized pi bond is when the same pi bond can occur in a different place due to different resonance structures. For example, in CO3^2-, the double bond could go on any of the oxygens, while the other two oxygens would have a single bond. As a result, the pi bond would be delocalized because it could occur on any of the resonance structures.

I hope that helps!

A delocalized pi bond is a bond when electrons can move to more than two nuclei. Usually they are found in resonance structures where there is a double bond.
