Learning outcomes - after studying this topic, you should be able to:

• describe the electron pair geometries and molecular shapes for molecules containing between 2 and 6 electron pairs
• assign molecular shapes based on Lewis structures and VSEPR theory
• explain the difference between polar bonds and polar molecules
• predict, based on molecular shape, whether a molecule will have a net dipole moment
• identify carbon-carbon single, double and triple bonds
• determine whether a molecule is polar

• Sections 5.4 and 5.5 (in Blackman, Bottle, Schmid, Mocerino and Wille, Chemistry, 3^rd Edition, 2015 (John Wiley) )

• Molecular geometry (in ChemWiki)
• Molecular shape (in Wikibooks General Chemistry)
