Delocalized pi bonds

Postby 805601399 » Sun Nov 21, 2021 11:06 pm

What are delocalized pi bonds and how can I identify them?

Hi! In delocalized pi bonds, the electrons are free to move around. If a molecule has resonance, it means that there is a delocalized pi bond.

hi there!

delocalized pi bonds occur when there are resonance structures. you can identfy them by first drawing the structure and seeing if there are any resonance forms, if there is resonance, you would then just count the number of pi bonds and can assume they are all delocalized.

I hope this helps!

I'm pretty sure a delocalized pi bond is a double bond that is spread out (or delocalized) among resonance structures. So in a molecule that has multiple structures involving the movement of a double bond (like C6H6) you would find a delocalized pi bond.

Delocalized pi bonds occur in resonance structures. The electron isn't fixed to a single bond/atom.

#16 on the Achieve HW has a good example of this. We see delocalized pi bonds in O3 for example because of its resonance structures. Since O3 has a double bond, and thus a pi bond, we know it must have a delocalized pi bond.

Delocalized pi bonds are found in compounds that have resonance structures because the resonance structures indicate that the electrons are not fixed to a single bond and are therefore free to move around.

A molecule has delocalized pi bonds if it has resonance. The electrons are delocalized here because there are not fixed to a set bond.

Delocalized mean that there are resonance, which means that although in our Lewis structure we assign pi bonds to specific atoms, in reality, the pi bonds are delocalized

Delocalized pi bonds exist if the molecule has resonance.
