Unit 8 - Advanced Bonding Concepts
- Compare the relative strengths of forces between molecules based on the melting point and boiling point of the substances.
- Compare the strength of the forces of attraction between molecules of different elements. (For example, at room temperature, chlorine is a gas and iodine is a solid.)
- Predict whether the forces of attraction in a solid are primarily metallic, covalent, network covalent, or ionic based upon the elements' location on the periodic table.
- Identify the elements necessary for hydrogen bonding (N, O, F).
- Given the structural formula of a compound, indicate all the intermolecular forces present (dispersion, dipolar, hydrogen bonding).
- Explain properties of various solids such as malleability, conductivity, and melting point in terms of the solid's structure and bonding.
- Explain why ionic solids have higher melting points than covalent solids. (For example, NaF has a melting point of 995°C while water has a melting point of 0° C.)

Changes of State (C5.4c-e)
- Explain why both the melting point and boiling points for water are significantly higher than other small molecules of comparable mass (e.g., ammonia and methane).
- Explain why freezing is an exothermic change of state.
- Compare the melting point of covalent compounds based on the strength of IMFs (intermolecular forces).
