Delocalized Bonds

[Melanie Krahn 1C]

Hello! Could someone please help explain to me the importance of delocalized bonds and how we are supposed to visually identify them in a given molecule?

In addition to this question, do the formal charges change significantly when there is a delocalized bond? Or would it generally be the same?

Delocalized bonds happen in resonance structures so if you know a compound/molecule has several possible structures, that might be an indication that there may be a delocalized bond.

I think it would depend on the molecule how greatly the formal charge is affected once you move the bond.

Delocalized bonds occur in resonance structures, where the electrons are equally shared between all the bonds.

There was an example given with Benzene (C₆H₆) where the structure was seen to have a Delocalized ring of 6 electrons, each given by the 1 unhybridized electron of each Carbon. I was wondering, in this case, does the delocalization of the electrons mean that they are not specifically "attached" to the Carbon they originated from? It seemed from the description that they were separated in some way but I was unsure of how exactly they were different from a regular electron cloud.
