Which of the following resonating structures is not correct for `CO_(2)` ? .

Options

A.
B.
C.
D.

Answer

To determine which of the given resonating structures for carbon dioxide (CO₂) is not correct, we need to analyze the possible resonance structures of CO₂.

### Step-by-Step Solution:

1. **Understand the Structure of CO₂**:
- Carbon dioxide (CO₂) consists of one carbon atom and two oxygen atoms.
- The carbon atom is in the center, and the two oxygen atoms are on either side.
- The molecular geometry of CO₂ is linear.

2. **Determine the Hybridization**:
- The hybridization of the carbon atom in CO₂ is sp, as it forms two double bonds with the two oxygen atoms.

3. **Draw the Lewis Structure**:
- The Lewis structure of CO₂ shows carbon double-bonded to each oxygen atom.
- Each oxygen atom has two lone pairs of electrons.

4. **Identify Resonance Structures**:
- The resonance structures can be formed by moving the lone pairs of electrons on the oxygen atoms.
- One possible resonance structure involves moving a lone pair from one oxygen to form a double bond with carbon, while the other oxygen becomes negatively charged.
- The other resonance structure can be formed similarly by moving the lone pair from the other oxygen.

5. **Evaluate the Given Structures**:
- Check each of the proposed resonance structures for CO₂.
- Ensure that each structure adheres to the octet rule and that carbon does not exceed its tetravalency (maximum of four bonds).

6. **Identify the Incorrect Structure**:
- Among the proposed structures, if any structure shows carbon forming five bonds, it is incorrect.
- Since carbon is tetravalent, it cannot exceed four bonds.

7. **Conclusion**:
- The structure that shows carbon forming five bonds is not a valid resonance structure for CO₂. Thus, this structure is the incorrect one.

### Final Answer:
The resonating structure that is not correct for CO₂ is the one where carbon forms five bonds.
