Dipole-Dipole Forces
• When polar molecules come in contact with each other
• partially positive end of a molecule is attracted to a partially negative end and vice-versa.
• Hydrogen bonding is a type of dipole-dipole bonding.

The HCl, or the hydrochloric acid, is attracted to one
another through dipole-dipole forces.

attracted to the partially negative oxygen. This is also considered a hydrogen bond, because the force of attraction between the
hydrogen of one molecule to an electronegative element, which is oxygen.
The partially positive hydrogen is attracted to the partially negative chlorine.
The water molecule is attracted to the other water molecules through dipole-dipole forces. The partially positive hydrogen is
• strength of intermolecular attractions increases with increasing polarity for molecules with about equal mass and size
• The bonds are stronger in solids(more closely packed together) than in liquids(molecules are loose)
