Delocalized Pi-Bonding

[Jasmine Wu 1L]

What is a delocalized pi-bond, and how do you find them?

Thanks! :)

A pi bond happens when two sets of electron orbitals involved in the bond overlap. A common example occurs in benzene. They are seen in resonance structures with different locations of double and triple bonds.

It is delocalized because the e- can move around, resulting in resonance structures. This is only seen when a pi-bond is present.

The easiest way to spot delocalized pi-bonding is in lewis structures that display resonance structures, as the pi-bond can move around and is therefore "delocalized." Just remember delocalized as not being local to one specific point in the structure.

So just to be clear, in order for there to be delocalized pi-bonding there must be at least a double bond between two atoms as well as a lone pair on one of the atoms?

For clarification, delocalized pi bonding happens when there is a molecule who's structure has some double and some single bonds, so has a resonance hybrid where each bond has partial double bond character?
