1. what kind of intermolecular forces act between a chlorine monofluoride molecule and a hydrogen bromide molecule
note: if there is more than one type of intermolecular force that acts, be sure to list them all, with a comma between the name of each force.

Dipole- Dipole force.

Explanation:

Here both Chlorine monofloride( ClF) and hydrogen bromide( HBr) both are highly polar molecules. Polar molecules have dipole intermolecular forces. Polar molecules are adhering to their neighbors atom and tend to have higher boiling points, than non-polar molecules. One polar molecule's positive end is drawn by another polar molecule's negative end and vice versa.
