Intermolecular Forces

The caffeine molecule can bond using hydrogen bonding, dipole dipole, and dispersion forces.

• In this case hydrogen bonding is taking place between hydrogen and hydrogen and also hydrogen and oxygen.
• Dipole Dipole takes place between two oppositely charged end of molecules. The O in one molecule is negatively charges which then bonds with the positively charged H of the other.
• Dispersion forces take place between all molecules that bond. This is caused by the erratic movement of electrons that form temporary dipoles between atoms in the molecules.
