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

• assign molecular shapes based on Lewis structures
• recognise four functional groups: aldehyde, alcohol, ketone and nitrile
• reconise three kinds of carbon-carbon bonds and know their names (alkane, alkene, alkyne) and shapes.

• 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)
