Here are the names and polarities of the given compounds:
-
CBr4
- Name: Carbon tetrabromide
- Polarity: Nonpolar
- Explanation: CBr4 has a symmetric tetrahedral shape, which cancels out the dipole moments.
-
BH3
- Name: Borane
- Polarity: Nonpolar
- Explanation: BH3 has a trigonal planar shape, and its symmetrical distribution makes it nonpolar.
-
SO4^2-
- Name: Sulfate ion
- Polarity: Nonpolar
- Explanation: The sulfate ion has a tetrahedral shape, and its symmetry results in no net dipole moment.
-
BrI5
- Name: Bromine pentaiodide
- Polarity: Polar
- Explanation: The BrI5 molecule has a square pyramid shape, leading to an asymmetrical distribution of electron density.
-
SiS2
- Name: Silicon disulfide
- Polarity: Nonpolar
- Explanation: SiS2 has a linear structure, and due to its symmetry, the dipoles cancel out.

OF6
- Name: Oxygen hexafluoride
- Polarity: Nonpolar
- Explanation: OF6 has an octahedral shape, which is symmetrical, leading to an overall nonpolar molecule.
-
PF3
- Name: Phosphorus trifluoride
- Polarity: Polar
- Explanation: PF3 has a trigonal pyramidal shape, which results in a net dipole moment.
-
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.
-
SeF4
- Name: Selenium tetrafluoride
- Polarity: Polar
- Explanation: SeF4 has a seesaw shape, which leads to an asymmetrical distribution of dipoles.
-
ClBr3
- Name: Chlorine tribromide
- Polarity: Polar
- Explanation: ClBr3 has a T-shaped geometry, leading to an overall net dipole moment.
