Attractive Forces Between Atoms or Molecules

At this point the only polar molecules we have discussed are those polar molecules that exhibit hydrogen bond intermolecular attractive forces The hydrogen bond intermolecular attractive force only occurs between molecules that contain an O-H N-H or F-H group However there is one more intermolecular attractive force that can occur in polar

The Chemistry Of Water

Hydrogen bonds are a much stronger type of intermolecular force than those found in many other substances and this affects the properties of water Figure 4 8: Intermolecular and covalent bonds (interatomic forces) in water Note that the diagram on the left only shows intermolecular forces The covalent bonds (interatomic forces) are between

Intermolecular force

Intermolecular forces (IMF) are the forces which mediate interaction between molecules including forces of attraction or repulsion which act between molecules and other types of neighboring particles e g atoms or ions Intermolecular forces are weak relative to intramolecular forces – the forces which hold a molecule together For example the covalent bond involving sharing electron

Quantum

In the natural sciences an intermolecular force is an attraction between two molecules or atoms They occur from either momentary interactions between molecules (the London dispersion force) or permanent electrostatic attractions between dipoles They can be explained using a simple phenomenological approach (see intermolecular force) or using a quantum mechanical approach
