BrF3 dominant intermolecular force

Answer 1

BrF is polar, its dipole moment is known, 1.4D . Dipole -dipole will be the strongest intermolecular force. Dispersion forces will also be present. The argument runs -

Dispersion forces are caused by the total number of electrons, compare BrF (number of electrons 44 with noble gases say Xenon, 54 electrons)

BrF decomposes around 200C , its boiling point which is considerably higher than the bp of xenon (-108 oC). Indicating factors other than disperison forces are at play causing the bp to be so high.

Answer 2

The dominant intermolecular force in BrF3 is dipole-dipole interactions. BrF3 is a polar molecule due to the difference in electronegativity between bromine and fluorine atoms, leading to the formation of permanent dipole moments. These dipole-dipole interactions help hold the molecules together in the solid or liquid state.

Answer 3

Dipole-dipole and dispersion exists in molecules BrF.

Answer 4

As this is a T-shaped molecule, it has dipole dipole intermolecular forces.

Answer 5

Dipole-dipole interactions exist in BrF.

Answer 6

These are dipole-dipole forces.
