What are dipole induced dipole forces?

Question

Ella Allen · Accepted Answer

It is the attractive force induced on a molecule by the presence of a polar molecule.

The partial charges on polar molecules cause the electron cloud of non-polar molecules to distort when they are near polar molecules, though this is not always the case. The second molecule becomes polar as a result of this distortion of its electron cloud, which gives it areas of partial positive and partial negative charges. The resulting partial charges interact favorably with their corresponding partial charges in the polar molecule that first induced them and behave exactly like those of a permanently polar molecule. As a result, the two molecules bind to one another, increasing the intermolecular forces within the molecule and influencing its reactions and characteristics.

undefined Dipole-induced dipole forces, also known as London dispersion forces or van der Waals forces, occur between molecules with temporary dipoles induced by the presence of nearby molecules with permanent dipoles. This results in attractive forces between the positive end of one molecule and the negative end of another, creating a temporary dipole in the initially nonpolar molecule.
