Problem page what kind of intermolecular forces act between a dichlorine monoxide molecule and a hydrogen bromide molecule?
marta [7]
Dichlorine monoxide has the same structure like that of water. So, this is a polar molecule. For polar molecules, the dominant intermolecular force would be dipole-dipole forces. For HBr, there is a force between two oppositely charged ions, H⁺ and Br⁻. So, the dominant intermolecular force is electrostatic attraction.
