Answer 1

Here are the names and polarities of the given compounds:

1. **CBr4**
- **Name**: Carbon tetrabromide
- **Polarity**: Nonpolar
- Explanation: CBr4 has a symmetric tetrahedral shape, which cancels out the dipole moments.

2. **BH3**
- **Name**: Borane
- **Polarity**: Nonpolar
- Explanation: BH3 has a trigonal planar shape, and its symmetrical distribution makes it nonpolar.

3. **SO4^2-**
- **Name**: Sulfate ion
- **Polarity**: Nonpolar
- Explanation: The sulfate ion has a tetrahedral shape, and its symmetry results in no net dipole moment.

4. **BrI5**
- **Name**: Bromine pentaiodide
- **Polarity**: Polar
- Explanation: The BrI5 molecule has a square pyramid shape, leading to an asymmetrical distribution of electron density.

5. **SiS2**
- **Name**: Silicon disulfide
- **Polarity**: Nonpolar
- Explanation: SiS2 has a linear structure, and due to its symmetry, the dipoles cancel out.

6. **OF6**
- **Name**: Oxygen hexafluoride
- **Polarity**: Nonpolar
- Explanation: OF6 has an octahedral shape, which is symmetrical, leading to an overall nonpolar molecule.

7. **PF3**
- **Name**: Phosphorus trifluoride
- **Polarity**: Polar
- Explanation: PF3 has a trigonal pyramidal shape, which results in a net dipole moment.

8. **CO2**
- **Name**: Carbon dioxide
- **Polarity**: Nonpolar
- Explanation: CO2 has a linear structure, and the equal electronegativity of the two oxygen atoms cancels out the dipoles.

9. **SeF4**
- **Name**: Selenium tetrafluoride
- **Polarity**: Polar
- Explanation: SeF4 has a seesaw shape, which leads to an asymmetrical distribution of dipoles.

10. **ClBr3**
- **Name**: Chlorine tribromide
- **Polarity**: Polar
- Explanation: ClBr3 has a T-shaped geometry, leading to an overall net dipole moment.
