Assessment Objectives

Detailed Breakdown: Chemical Bonding

• Describe the structure of a metallic lattice and a giant ionic lattice.
• State the differences between discrete molecular and giant covalent structures.
• Predict the molecular geometry and bond angles for molecules with up to 6 electron domains using VSEPR.
• Differentiate between polar bonds and polar molecules.
• Identify the specific intermolecular forces present in a substance based on its Lewis structure.
• Describe the electrical conductivity of ionic compounds in different states.
• Compare the boiling points of $\ce{HF, HCl, \text{ and } HBr}$ and explain the trend using IMF theory (including the hydrogen bonding anomaly).
• Relate lattice enthalpy factors (ion charge and size) to the relative melting points of $\ce{NaCl}$ vs $\ce{MgO}$.
• Explain the electrical conductivity and strength of Graphite vs Diamond based on their hybridization and structure.
