Which of the following species have the same shape?

Options

A. `CO_(2)`
B. `CCl_(4)`
C. `O_(3)`
D. `NO_(2)^(-)`

Explanation

To determine which of the given species have the same shape, we will analyze each species one by one and identify their molecular geometry.

### Step-by-Step Solution:

1. **Identify the First Species: Carbon Dioxide (CO₂)**
- Carbon dioxide consists of one carbon atom double bonded to two oxygen atoms.
- The molecular geometry of CO₂ is linear due to the arrangement of the double bonds and the absence of lone pairs on the central carbon atom.
- **Shape:** Linear

2. **Identify the Second Species: Chlorine Tetrafluoride (ClF₄)**
- Chlorine tetrafluoride has one chlorine atom bonded to four fluorine atoms.
- The molecular geometry of ClF₄ is tetrahedral because all four bonds are equivalent and there are no lone pairs on the chlorine atom.
- **Shape:** Tetrahedral

3. **Identify the Third Species: Ozone (O₃)**
- Ozone consists of three oxygen atoms, with one of the oxygen atoms forming a double bond with another oxygen atom and a single bond with the third oxygen atom.
- The presence of a lone pair on the central oxygen atom causes the molecule to adopt a bent shape.
- **Shape:** Bent

4. **Identify the Fourth Species: Nitrite Ion (NO₂⁻)**
- The nitrite ion has one nitrogen atom bonded to two oxygen atoms, with one of the bonds being a double bond.
- Similar to ozone, the presence of a lone pair on the nitrogen atom results in a bent molecular geometry.
- **Shape:** Bent

### Conclusion:
- From the analysis, we find that:
- Carbon Dioxide (CO₂) is linear.
- Chlorine Tetrafluoride (ClF₄) is tetrahedral.
- Ozone (O₃) is bent.
- Nitrite Ion (NO₂⁻) is also bent.

Thus, the species that have the same shape are **Ozone (O₃) and Nitrite Ion (NO₂⁻)**, both of which are bent in shape.

### Final Answer:
Ozone (O₃) and Nitrite Ion (NO₂⁻) have the same shape.
