Resonance Structures and Sigma & Pi Bonds

[Isaac Wen]

Hi! If a compound has resonance (let's say it has bond lengths between a single bond and a double bond), would it have both a sigma bond and a pi bond just like a double bond would?

[Edward Tang 1k]

Resonance indicates the presence of delocalized electrons, which are, in fact, the pi bonds. The pi bonds in resonances structures are delocalized and travels between different pairs of two atoms. So to answer your question, yes there are pi and sigma bonds in molecules with resonances.

Yes, resonance structures would have sigma and pi bonds just like a double or triple bond would.

[Emma Strassner 1J]

All resonance structures have sigma and pi bonds, and when drawing the structures you just change where they go.

[Serena Song 1A]

Yup! Resonance structures have sigma and pi bonds. I believe the pi bonds in resonance structures are specifically called delocalized pi bonds.

[Linette Choi 3L]

Yup, if the resonance structure still had the double bond then it would still have the sigma and pi bonds. The bonds would just be delocalized along with the electrons since resonance structures move them around.

Hi! Resonance structures would still have sigma and pi bonds and all that would change is their location.
