Answer:
Dipole - Dipole forces
Explanation:
The intermolecular forces that exists between HBr and H₂S is the dipole - dipole forces of attraction.
H₂S and HBr are both polar compounds because of the high electronegativity difference between hydrogen and sulfur or bromine.
- Dipole - Dipole attractions are forces of attraction existing between polar molecules (unsymmetrical molecules) i.e. molecules having permanent dipoles.
- Such molecules line up such that the positive pole of one such molecule attracts the negative pole of another.
- This is what occurs between the molecules of HBr and H₂S.
