What are the intermolecular forces in iodine monochloride?

Answer 1

#"ICl"# has both dipole-dipole and London dispersion forces.

The #"I-Cl"# bond is polar covalent.

Admittedly, it is not very polar, because #ΔEN# is only 0.50 (corresponding to about 6 % ionic character).

However, there is still a small dipole moment, so the molecule has dipole-dipole forces.

A molecule of #"ICl"# can still have temporary fluctuations in electron density, and these will induce fluctuations in nearby #"ICl"# molecules.

Thus, #"ICl"# also has London dispersion forces.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
