Question

What are all the intermolecular forces present in a sample of BrF?

ion-dipole

London

Hydrogen bonding

dipole-dipole

Answer 1

The intermolecular forces present in a sample of BrF are London dispersion forces, dipole-dipole forces, and hydrogen bonding.

Step-by-step explanation:

The intermolecular forces present in a sample of BrF are London dispersion forces, dipole-dipole forces, and hydrogen bonding.

1. London dispersion forces: These are the weakest intermolecular forces and occur between all atoms and molecules, regardless of polarity. They result from temporary fluctuations in electron distribution, creating temporary dipoles.
2. Dipole-dipole forces: These forces occur between polar molecules, where the positive end of one molecule is attracted to the negative end of another molecule. BrF is a polar molecule, so it experiences dipole-dipole forces.
3. Hydrogen bonding: Hydrogen bonding occurs when a hydrogen atom is bonded to a highly electronegative atom (such as oxygen, nitrogen, or fluorine) and is attracted to a lone pair of electrons on a neighboring molecule. BrF does not have hydrogen bonding because it does not contain hydrogen bonded to an electronegative atom.

Answer 2

dipole-dipole

Step-by-step explanation:

Intermolecular forces exists between the molecules of a substance in a particular state of matter.

The type of intermolecular forces present in a substance is determined by the electronegativity difference between the atoms that compose the substance.

There is a non zero electronegativity difference between Br and F hence the molecule is polar and the intermolecular forces between the molecules of BrF are dipole-dipole forces.
