Chapter 11 - Theories of Bonding
Sections 11.1 - 11.2
11.1 Valence Bond (VB) Theory and Orbital Hybridization
Concepts
- Be able to discuss the main ideas of valence bond theory: orbital overlap, opposing electronic spins, and hybridization; as a way of explaining molecular shapes.
- Assigned problems: 11.1, 11.2
- Be able to describe how orbitals mix to form hybrid orbitals with different spatial orientations.
- Assigned problems: 11.3, 11.4
Skills
- Be able to use molecular shape to postulate the hybrid orbitals used by a central atom in a molecule.
- Assigned problems: 11.5, 11.6, 11.7, 11.9, 11.10, 11.12, 11.13, 11.15, 11.17, 11.19
- Sample problems: 11.1
10.2 - Valance-Shell Electron-Pair Repulsion (VSEPR) Theory and Molecular Shape
Concepts
- Be able to describe the distinction between end-to-end and side-to-side overlap an the origin of sigma (σ) and pi (π) bonds in simple molecules..
- Be able to discuss why π bonding restricts rotation around double bonds.
Skills
- Be able describe the types of orbitals and bonds in a molecule.
