### Understanding Intermolecular Forces and Boiling Points This educational guide explores the relationship between boiling points and intermolecular forces of various molecules. The table below is designed to be completed with research and analysis. #### Instructions: 1. **Look up the values for the boiling points on the internet.** 2. **Predict all the different kinds of intermolecular forces present and explain why you think these are present. Finally, underline the strongest IMF.** 3. **Explain the trend seen in this table.** #### Table of Molecules: | Molecule | Boiling point (°C) | Intermolecular forces present | |----------|-------------------|-------------------------------| | CH₄ | | | | C₂H₆ | | | | HCl | | | | HF | | | | H₂O | | | #### Molecules to Investigate: - **Methane (CH₄)** - **Ethane (C₂H₆)** - **Hydrochloric acid (HCl)** - **Hydrofluoric acid (HF)** - **Water (H₂O)** #### Educational Objectives: - Learn the concept of intermolecular forces (IMF) including London dispersion forces, dipole-dipole interactions, and hydrogen bonding. - Analyze how IMFs affect the boiling points of substances. - Discover trends in boiling points relative to molecular structure and types of bonding. This study sheet is a resource provided by the Department of Chemistry at Florida International University.

States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
