Intermolecular Forces: The forces present between the molecules of a substance are known as intermolecular forces. Such forces exist in the three states of matter and are responsible for many structural features and physical properties of matter. In addition, these are intermolecular forces that exist within each molecule, influence the chemical properties of the substance. These forces are weak forces. These forces arise due to the following type of interactions- Dipole-dipole interaction (or Keesom Forces): These type of forces occur in molecules which have permanent electrical dipoles such as HCl, NH3, H2O etc. These forces arise due to electrostatic interactions … Continue reading Intermolecular Forces
