Extra credit essay on Intermolecular Forces

With this new information of the world I decided to teach some on my fellow students and teachers about the chemistry world of Intermolecular forces. Defining this word would be very complex and boring so to summarize this long exhausting word that I have to type several times because of my teacher Mr.John­John or as others call him Mr.GreenHead A.K.A.
Mr.Johnson. Which pretty much tells the difference between substances and compounds with the structur, syways
Intermolecular forces are forces of attraction or repulsion which act between neighboring particles (atoms, molecules or ions). They are weak compared to the intramolecular forces, the forces which keep a molecule together. In general, intermolecular forces can be divided into several categories. The most popular prominent types are
Strong ionic attraction which recalls lattice energy and its relations to properties of solid. The more ionic, the higher the lattice energy. Then you have the
Intermediate dipole­dipole forces which has substances whose molecules have dipole moment have higher melting point or boiling point than those of similar molecular mass, but their molecules have no dipole moment. When
Weak London dispersion forces or van der Waal's forces which always operates in any substance. The force arisen from induced dipole and the interaction is weaker than the dipole­dipole interaction. In general, the heavier the molecule, the stronger the van der Waal's force of interaction. For example, the boiling points of inert gases increase as their atomic masses increases due to stronger Landon dispersion interactions. Next are the
Hydrogen bond which has certain substances such as H
O, HF, NH
2
3 form hydrogen bonds, and the formation of which affects properties (mp, bp, solubility) of substance. Other compounds containing OH and NH
2 groups also form hydrogen bonds. Molecules of many organic compounds such as alcohols, acids,

amines, and aminoacids contain these groups, and thus hydrogen bonding plays a important role in biological science. But for
Covalent bonding it’s really intramolecular force rather than intermolecular force. It is mentioned here, because some solids are formed due to covalent bonding. For example, in
