alleryThe structures contributing to a resonance hybrid are called:
ACompressed structures
BCanonical structures
CCationic structures
DCatalytic structures
Answer & Solution
Correct answer: B. Canonical structures
1. The real molecule is a blend of several drawings.
2. Those component drawings have a formal name.
3. The structures shown constitute the canonical structures or resonance structures.
4. So the answer is canonical structures.
