NON-COVALENT BONDS
1. HYDROGEN BONDING
This is an interaction involving a hydrogen atom located between a pair of other atoms that have a high
affinity (strong attraction) for electrons.
These bonds are weaker than ionic and covalent bonds but stronger than van der Waals forces.
Example
Water (H2O)
The bond is between the HYDROGEN ATOM OF ONE WATER MOLECULE and the OXYGEN ATOM OF
ANOTHER WATER MOLECULE.
*NOTE: The bond is NOT between the two hydrogen atoms in one water molecule.
The attractive force between water molecules is a dipole interaction.
*Dipole-dipole forces: These are attractive forces between the positive end of one polar molecule
and the negative end of another polar molecule.
