The strongest intermolecular force between two molecules of water in ice is hydrogen bonding.
The strongest intermolecular force between hydrogen chloride molecules is dipole-dipole interactions. Hydrogen chloride is a polar molecule with a permanent dipole moment, so the positive hydrogen end of one molecule is attracted to the negative chlorine end of another molecule, leading to dipole-dipole interactions.
To determine the strongest intermolecular force in a substance, you need to consider the types of molecules present. Look for hydrogen bonding, which is the strongest intermolecular force. If hydrogen bonding is not present, then consider dipole-dipole interactions and London dispersion forces in determining the strength of intermolecular forces.
This could be a catch question! NaBr is ionic and there are no molecules. The inter ionic forces are electrostatic.

The strongest intermolecular forces that would exist between molecules of NO would be dipole-dipole attractions. There are no hydrogen bonds formed, and so dipole-dipole would be the strongest. There will also be dispersion forces, but these are weaker than dipoles.

Hydrogen bonds between molecules
The strongest intermolecular force in ammonia is hydrogen bonding. This occurs because the nitrogen atom in ammonia can form a hydrogen bond with a hydrogen atom from another ammonia molecule, resulting in a relatively strong attraction between the molecules.
Hydrogen bonding is typically the strongest intermolecular force due to the strong dipole-dipole attraction that occurs between molecules with a hydrogen atom bonded to a highly electronegative atom like nitrogen, oxygen, or fluorine.
Water (H2O) has stronger intermolecular forces than ammonia (NH3) due to hydrogen bonding in water molecules. Hydrogen bonding is a type of intermolecular force that is stronger than the dipole-dipole interactions present in ammonia molecules.

The strongest intermolecular force present in hydrogen bromide (HBr) is dipole-dipole interaction.
