Intramolecular and Intermolecular Bonds!!

In todays class we learned about Intramolecular and Intermolecular Bonds!! But before we start here is something to ponder over.

Here are the types of bonds:

Intramolecular bonds exist within a molecule.

-Covalent, Ionic

Intermolecular bonds exist between molecules.

-The stronger the molecular bond the higher the melting point and boiling point are.

-two types of intermolecular bonds are:

1. Van der Waals bonds

2. Hydrogen bonds

-they are based on electron distribution

-There are two categories that they can fall under:

1. Dipole-Dipole bonds

- if a molecule is polar the positive end of one molecule will be attracted to the negative end of the other molecule.

2. London Dispersion Forces (LDF)

-LDF is present in all molecules

-creates the weakest bonds

-A non polar Dipole-Dipole forces do not exist

-Electrons are free to move around and at some point may be at one side of the atom which leaves an open area to form a temporary dipole. This would form a weak bond on that open side.

-The more the molecules in a bond the stronger the LDF can be.

Hydrogen Bonding

-Hydrogen is bonded to certain elements [ (N)itrogen, (O)xygen, (F)lourine. ] where the bond is highly polar.

-this is a very strong intermolecular bond.
