What type of intermolecular forces exist forces between HBr and H2S? Explain

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.
