Hybridization and Resonance Structures

Postby Neel Bonthala 2G » Wed Nov 25, 2020 5:55 pm

Do all molecules with resonance structures have unhybridized molecules that contribute to delocalization of electrons? In the benzene example in lecture, each C in benzene had 3 hybridized orbitals, but then it had 1 unhybridized p orbital that contributed to its resonance. What exactly is the model for hybridized orbitals (like sp^3), and how is it graphed on the internuclear axis as compared to something we went over in lecture, like p orbitals?

To answer the first part of your question, yes, all molecules with resonance have unhybridized molecules. Since resonance typically implies that there is a double bond, there must be an unhybridized molecule to create the pi bond.

In terms of hybridized orbitals, this site has a lot of diagrams that may better help visualize how hybridized orbitals compare to unhybridized orbitals.


Hope this helps!
