Study Notes
- Intermolecular forces are attractive and repulsive forces between molecules of a substance.
- They are responsible for the physical characteristics of a substance and affect its condensed states.
- Boiling point is proportional to the strength of intermolecular forces.
- Dipole-dipole interactions are attractive forces among polar molecules.
- Ion-dipole interactions arise between ions and polar molecules.
- Ion-induced dipole interactions occur when a non-polar molecule is polarized by an ion placed near it.
- Dipole-induced dipole interactions occur when non-polar molecules are transformed into induced dipoles due to the presence of a polar molecule nearby.
- Dispersion forces or London forces are the weakest force and arise due to the movement of electrons.
- The boiling point of a substance can be used to compare the strengths of intermolecular forces.
- BYJU'S - The Learning App provides further information on intermolecular forces.
