Dipole-dipole interactions occur between polar molecules. These are molecules that have a net dipole moment due to the presence of polar bonds. Polar bonds are formed when there is a significant electronegativity difference between the atoms involved in the bond, leading to a charge separation within the molecule.

1. He and H2: Both helium (He) and hydrogen (H2) are nonpolar molecules. Therefore, there are no dipole-dipole interactions between them.

2. Ne and He: Both neon (Ne) and helium (He) are nonpolar molecules. Therefore, there are no dipole-dipole interactions between them.

3. HCl and HCl: Hydrogen chloride (HCl) is a polar molecule because there is a significant electronegativity difference between hydrogen (H) and chlorine (Cl). Therefore, there are dipole-dipole interactions between HCl molecules.

4. H2 and Cl2: Both hydrogen (H2) and chlorine (Cl2) are nonpolar molecules. Therefore, there are no dipole-dipole interactions between them.

So, the pair that has dipole-dipole interactions is HCl and HCl.
