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

• identify the main types of intermolecular forces, and explain their importance in the formation of condensed phases
• predict trends in the strength of intermolecular forces with, for example, charge, dipole moment and molecular weight
• identify the relationship between boiling point, vapour pressure, enthalpy of vapourization and the strength of intermolecular forces
• use intermolecular forces to explain the concept of “like dissolves like"
• explain the hydrogen bond, identify the elements and bonds that  may undergo hydrogen bonding, and draw the structure of a hydrogen bond
• relate the strength of intermolecular forces to boiling points, and explain why this is a useful measure
• explain amphiphilicity and define amphiphiles and surfactants, and describe their key properties

• Sections 6.7 and 6.8 (in Blackman, Bottle, Schmid, Mocerino and Wille, Chemistry, 3^rd Edition, 2015 (John Wiley))

• Intermolecular forces (in ChemWiki)
