Intermolecular Bonds!

There are two types of Bonds: INTRAmolecular bonds and INTERmolecular bonds.

Intramolecular: Exist within a molecule such as Ionic and covalent bondings.
Intermolecular: Exist between molecules. There are two types of Intermolecular bonds: Van der Waals bonds and hydrogen bonds.

Van der Waal Bonds:
- This bonding is based on electron distribution.
- Dipole-Dipole bonds: positive is attracted to negative end. Only occurs in polar molecules.

London Dispersion Forces: (LDF)
- LDF is present in all molecules
- These are the weakest bonds
- If a substance is non-polar Dipole-Dipole forces doesn't exist.
- Electrons are free to move around and will randomly grouped on one side of the molecule.
- This creates a temporary dipole and can cause a weak bond to form.
- The more electronegativity in the molecules the stronger the LDF can be.

Hydrogen Bonding:
- If hydrogen is bonded to certain elements (F,O,N) the bond is highly polar
- This forms a very strong inermolecular bond.
