What is a resonance hybrid? How does it differ from the resonance structures drawn for a molecule? Select all that apply.?
I'm having issues with this right now, here are the options.
A resonance hybrid is a mixture or average of the various resonance structures that comprise it.
A resonance hybrid represents the true structure of the molecule or ion it represents.
A resonance hybrid represents one of the structures that the molecule or ion "jumps" or "cycles" through.
A resonance hybrid is a single resonance structure.

Each of the resonance structures is an approximation. The reality is the hybrid is a continuous electron structure that is a blending (or hybridisation) of each of the drawn resonance form.
The first two options are correct.
The third is more a description to help you think about things. The molecule doesn't really do these jumps, but sometimes it can help thinking about things to visualise it this way. Just be aware this isn't what is really happening.
The fourth is definitely not correct. A resonance hybrid is a blending of all the resonance structures, not a single resonance structure.
Enjoy :)
