induced dipole

What is an induced-dipole and how is it different from a dipole?

Induced dipole occurs when a nonpolar moelcule is turned dipole by an ionic molecule. Whereas dipole moments occur when the molecule already has a different charge

An induced dipole occurs when a molecule that would not usually possess a dipole forms a dipole due to integration with a molecule containing a dipole. For example, the polarity of HF induces a dipole in N2, a usually non polar molecule. The permanent dipole moment induces a dipole moment, and this is a favorable interaction.

In addition to the examples listed here, there are induced dipole-induced dipole interactions between two nonpolar molecules. This arises from a temporary dipole moment in a nonpolar molecule resulting from random uneven electron distribution, which in turn can induce another temporary dipole in a nearby nonpolar molecule.

An induced-dipole occurs when a temporary dipole occurs causing/inducing a dipole in a nonpolar molecule. On the other hand, a permanent dipole occurs when a polar molecule is always more elctronegative than the other molecule.
