# What are the intermolecular forces in iodine monochloride?

Aug 18, 2017

#### Answer:

$\text{ICl}$ has both dipole-dipole and London dispersion forces.

#### Explanation:

The $\text{I-Cl}$ 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 $\text{ICl}$ can still have temporary fluctuations in electron density, and these will induce fluctuations in nearby $\text{ICl}$ molecules.

Thus, $\text{ICl}$ also has London dispersion forces.
