“hydrogen bonds Dispersion forces are the weakest intermolecular force (one hundredth-one thousandth the strength of a covalent bond), hydrogen bonds are the strongest intermolecular force (about one-tenth the strength of a covalent bond).”
<u>The London forces</u>: all molecules have them, they are proportional to the molecule's weight.
<u>The dipole-dipole</u>: this are the result of the interaction between two opposite poles of two polar molecules. This forces are stronger than the London ones.
<u>The hydrogen bonds</u>: This forces are the stongest of the intermolecular forces and happen with the interation between the hydrogen of a moelcule and a very electronegative atom of another molecule. This atoms can be F, O or N.
