How are resonance forms and resonance hybrids related, according to the text?
- Resonance forms are experimental entities while resonance hybrids are imaginary images.
- Each resonance hybrid is exactly one of its resonance forms at any given time.
- Resonance hybrids are a combination of all their resonance forms at all times.
- Resonance hybrids have some characteristics in common with their resonance forms but are not exactly any one form at any given time. (correct)
What is the significance of the double-headed arrows between Lewis structures in resonance theory?
What is the significance of the double-headed arrows between Lewis structures in resonance theory?
- They show that the structures can interconvert rapidly. (correct)
- They represent the movement of electrons between the structures.
- They denote a chemical equilibrium between the different structures.
- They indicate that the structures are equally likely to exist.
