Dipole-dipole force

Explanation:

In the HI molecule, the difference in electronegativity is:

ΔEN = |EN (H) - EN (I) | = |2.1 - 2.5| = 0.4

Since ΔEN > 0, the bond is covalent polar and the molecule is polar (dipole).

In the ClF molecule, the difference in electronegativity is:

ΔEN = |EN (Cl) - EN (F) | = |3.0 - 4.0| = 1.0

Since ΔEN > 0, the bond is covalent polar and the molecule is polar (dipole).

HI and ClF interact through a dipole-dipole force.

Kamryn Bridges · Answer 2

Answer: - dipole-dipole

Explanations: - Both HI and ClF are polar molecules as the bonding is between two different non metals. Polar molecules have dipole intermolecular forces. When there are two polar molecules and it asks about the forces between them then it is dipole-dipole as there is an interaction between the opposite partial charges of the molecules. Positive end of one polar molecule is attracted by the negative end of another polar molecule and vice versa.
