Which of the following statement is incorrect about resonance?

Options

A. The most stable resonance structure explains
all the characteristics of a species.
B. All resonating structures remain in equilibrium.
C. Resonance hybrid has maximum similarity with
most stable resonating structure.
D. Resonance hybrid is real.

Answer

To determine which statement is incorrect about resonance, we need to analyze each statement provided in the question.

### Step-by-Step Solution:

1. **Understanding Resonance**:
- Resonance is a phenomenon in chemistry where a single Lewis structure cannot adequately represent a molecule. Instead, multiple structures (resonance structures) are used to depict the delocalization of electrons within the molecule.

2. **Evaluating Each Statement**:
- **Statement 1**: "The most stable resonance structure explains all the characteristics of a species."
- This statement is incorrect because while the most stable resonance structure can explain many characteristics, it does not explain all the properties of the molecule. Resonance structures collectively contribute to the overall characteristics of the molecule.

- **Statement 2**: "All resonating structures remain in equilibrium."
- This statement is also incorrect. Resonance structures are not in equilibrium; they are simply different ways to represent the same molecule. They do not exist independently and are not isomers.

- **Statement 3**: "Resonance hybrid has a maximum similarity with the most stable resonating structure."
- This statement is incorrect as well. The resonance hybrid is a composite of all resonance structures and does not necessarily have maximum similarity with the most stable one. It represents an average of all contributing structures.

- **Statement 4**: "Resonance hybrid is real."
- This statement is incorrect too. The resonance hybrid is a theoretical construct and does not correspond to a real structure. It is a way to visualize the delocalization of electrons.

3. **Conclusion**:
- All four statements provided in the question are incorrect regarding resonance.

### Final Answer:
All the statements about resonance are incorrect.
