Which of the following molecule/moleculas will have zero dipole moment ?
`CO_(2), H_(2)O C Cl_(4), CHCl_(3), BF_(3), BeF_(2), NH_(3)`.

Explanation

To determine which of the given molecules have a zero dipole moment, we need to analyze the molecular geometry and the polarity of the bonds in each molecule. A molecule will have a zero dipole moment if it is symmetrical, meaning that the dipoles of the individual bonds cancel each other out.

### Step-by-Step Solution:

1. **CO₂ (Carbon Dioxide)**:
- **Geometry**: Linear
- **Dipole Moment**: The two C=O bonds are equal in magnitude but opposite in direction. Therefore, they cancel each other out.
- **Conclusion**: CO₂ has a zero dipole moment.
