Explanation of Poster:

For my poster, I chose to cover the topic of intermolecular forces and how intermolecular forces cause interactions between polar and non-polar molecules. I decided to include the three main types of forces, starting from the weakest of the three forces, London Dispersion Forces, moving into Dipole-dipole Forces, and ending with the strongest of the forces, Hydrogen Bonding Forces. I included three diagrams alongside the definitions of the forces which show how electron density and polarity relate to each other and how dipoles visually demonstrate the partial negative and partial positive ends of a particle. I drew one of the diagrams myself but used photos for the two other diagrams due to the complexity of the diagrams, it was difficult trying to draw them myself on canva . I also thought it important to add that London Dispersion Forces occur in every molecule, polar or non-polar. This being due to temporary dipoles created from random electron movement in molecules. I think the way I outlined my poster allows for the viewer to be able to determine the “scale” of these forces and how each force interacts in polar and non-polar molecules. I believe ending my poster with hydrogen bonding works well with my outline. The prior knowledge of the two previous forces allows the viewer to be able to build previous knowledge up for understanding how hydrogen bonds work.

I chose to cover intermolecular forces for this unit project because I found it very fascinating. I had previously only known about hydrogen bonds before this unit but I hadn’t really understood the atomic level of how polarity works. Being able to apply the knowledge of electron density domains and the nature in which electrons move through shells absolutely opened up a new visualization of how I see polarity. It was interesting to find out that every molecule has some level of intermolecular forces, through the formation of temporary dipoles. 

Visually, I thought my poster would look best with a big colorful title, a few subtitles, and a diagram for each subtitle. I also made sure to include my references that I used to refresh on the topics and definitions of each force. The openstax chemistry textbook was very helpful in helping to make sure I was correct in my information, diagrams, and definition. I read through most of the intermolecular forces chapter for our sticky particles lab and learned how intermolecular forces affect boiling points and evaporation percentages of substances.I found out that the more intermolecular forces in a substance, the higher the boiling point. Hydrogen bonds have the most effect on boiling points, which is then followed by dipole-dipole, then London dispersion forces. Molecules with higher polarity, which equates to higher intermolecular forces, will cause the solution's boiling point to increase. The molecules in the solvent and the water molecules in the solution both have forces that interact with one another. A solution with high polarity molecules as the solute will evaporate more quickly and have a higher boiling point.
