Sub Topic Name : Dipole - Dipole Forces |
• Attractive forces between polar molecules are called dipole-dipole forces. • Dipole-dipole forces act between molecules having permanent dipole. • Ends of the dipoles possess “partial charges” and these charges are shown by delta (?). • This interaction is stronger than the London forces but is weaker than ion-ion interaction because only partial charges are involved. • The attractive force decreases with the increase of distance between the dipoles.
molecule, dipole, ion, partial charge
Magnets have two poles and therefore are a di-pole.

Magnet | A magnet has two poles; the north pole attracts a south pole on a different magnet. |
Dipole-dipole forces are found between polar molecules e.g. HCl.
Dipole-dipole forces are attractive forces between polar molecules that aid in formation of many vital molecules E.g. red blood cells.
