Question: Is a hybrid structure and a superposition the same thing? (I'm interested in the case of benzene)

Read many sources but they were contradictory..

Please help!
Thanks!

No. Resonance hybrids represent real molecular orbitals that cannot be well represented by conventional chemistry notation. They are not superpositions of molecular orbitals. See the discussion below for more details.

Ok, but does benzene have a superposition as well as a hybrid structure?

Superpositions of energy eigenstates normally only come into play when you electronically excite a molecule (for example, when the molecule is interacting with light).
