I. Introduction
The attraction forces between molecules are called intermolecular forces. It is the non-ideal behavior of gases. On the other hand, the attraction forces within the molecule are called intramolecular forces. (Chang, 2014)
There are different types of intermolecular forces. These are dipole-dipole, dipole-induced dipole, ion-induced dipole, and London dispersion forces. The dispersion force, also known as van der Waals force, is the weakest force. It happens when temporary dipoles are induced in atoms or molecules. It usually increases proportionally with molar …show more content…
The liquids that were tested are water, ethanol, kerosene, and liquid detergent. The physical property of water is significantly similar to ethanol. On the other hand, kerosene is a complete opposite of water. This is because water and ethanol are polar molecules while kerosene is a non-polar molecule. Additionally, liquid detergent has been classified as both polar and non-polar molecule. Moreover, the greater number of intermolecular forces of attraction present in a molecule, the stronger it is. Water and ethanol both have dispersion forces and hydrogen bonding while kerosene only has dispersion force. It means to say that there is a greater energy needed in order to break the bond that holds the molecules together.
In conclusion, intermolecular forces increase direct proportionally with increasing polarization. It should also be noted that the arrangement of the strength of intermolecular forces increase from dispersion, dipole-dipole, hydrogen bonding, to ion-dipole. Lastly, the boiling point of a molecule increases directly proportionally with molecular weight and surface
