Dipole-Induced Dipole Forces Quiz

Study Notes

Attractive Forces Between Molecules

Dipole-induced dipole forces arise between polar and non-polar molecules.
Larger atoms experience a greater influence from an electric dipole, affecting their electron clouds.
The electric field of a permanent dipole distorts the electron cloud, leading to an induced dipole moment.
The interaction energy increases with the distance (r) and depends on:
- The dipole moment of the polar molecule
- The polarisability of the non-polar molecule
Larger molecules exhibit higher polarisability which enhances attractive interactions.
A high dipole moment in polar molecules, combined with high polarisability in non-polar molecules, strengthens attractive forces.

London Forces

London forces, or dispersion forces, are present between all types of molecules, including:
- Polar molecules with each other
- Polar and non-polar molecules

Solubility and Intermolecular Forces

Ionic substances tend to dissolve in highly polar solvents, such as water, through a process called hydration.
The intermolecular forces involved in this solubility are known as ion-dipole forces.
In water, hydrogen atoms exhibit partial positive charges while oxygen holds a partial negative charge.
Water molecules organize around ions so that the positive end of the dipole faces anions, and the negative end approaches cations, facilitating solubility.
