Dipole induced dipole

[Dalayna Ortiz 1F]

What are some examples of dipole induced dipole and how do you spot it?

Hello,
We have dipole-induced dipole interactions when we have one polar molecule and a non-polar molecule. A good example is water, which is a polar molecule, and let's say carbon tetrachloride (CCl4). The negative charge on the water molecule will push the electrons to a different region making it possible to have this weak attractive force between the molecules.

Hello, this is a good question and I wanted to elaborate more on the previous post.

A dipole-induced dipole interaction occurs when a polar molecules (which have permanent dipoles), interact with nonpolar molecules, which causes a temporary distortion of the electron cloud of the nonpolar molecule (temporary dipole). Examples include H2O (polar) & noble gases (ex. xenon or argon) interactions, or a molecule like CCl4 (nonpolar) interacting with water, where the water molecule induces a temporary dipole in the nonpolar molecule due to its polarity.

Key points about dipole-induced dipole interactions:

One of the molecules involved must have a permanent dipole moment (a polar molecule).
The other molecule will be nonpolar, meaning it has no permanent dipole moment, but its electron cloud can be temporarily distorted by the polar molecule.
