After studying chapters 12.1, 13, and 14.1, you should be able to:
· Explain why most atoms form chemical bonds.
· Differentiate among properties of ionic, covalent, and metallic bonds.
· Compare and contrast the properties of ionic and molecular compounds.
· Classify bonds as ionic, covalent, or polar based on electronegativity differences.
· Create Lewis structures for covalent compounds containing single, double, and triple bonds, including resonance structures and exceptions to the octet rule.
· Use covalent radii to calculate bond lengths.
· Explain the modern interpretation of resonance bonding.
· Calculate the formal charge on atoms in molecules and evaluate Lewis structures on the basis of formal charge.
· Describe the shapes of simple covalently bonded molecules using VSEPR theory.
· Use bond dipoles to predict molecular dipoles.
· Define dipole and compare the strengths of intermolecular forces based on dipole moments.
· Describe hybrid orbitals and use hybridization theory to explain the bond angles in compounds.
· Differentiate sigma and pi bonding, and saturated and unsaturated carbon compounds.
· Define, explain, and give examples of isomerism.
· Use molecular orbital theory to discuss bonding in diatomic molecules
· Determine bond order and correlate bond order, bond energy, and bond length.
