Intermolecular forces play an essential role in holding our world - and us - together. We then show the emerging areas of their applications, mainly medical and . In this lab, by using your powers of observation, and by conducting a few simple tests, you will identify a series of unknowns and explain what types of intermolecular forces are present in the substances. The Kinetic Molecular Theory states that: (1) Matter is composed of small particles. While both are used to hold chemical systems together, they each introduce their own specific qualities into structures. Explain using the results of this experiment.

Virtual Tour: Intermolecular Forces - Ionic, Polar, Non-polar, Hydrogen Bonding (2) The molecules interact with one another through attractive forces. by electrons of adjacent atoms forming temporary dipoles (referred to as dipole-induced dipole At the end of this simulation, you will be able to: Describe how dispersion forces, dipolar forces, and hydrogen bonding between molecules arise, Identify molecular motifs and features that may contribute to intermolecular force induction, Predict the types of intermolecular forces present between different molecules. H*2P0P034R04R(J As the intermolecular force gets stronger it takes more energy to move the particles far away from each other.
