CHEM1901 - Resources for Week 7

Topics and Learning Outcomes

  • Gas Laws
    •  use the ideal gas law to relate the number of moles, pressure, volume and temperature of a gas
    •  relate gas density and molar mass
    •  convert between the common units of pressure (atm, Pa and mmHg)
    •  use the appropriate value of the gas constant, R
  • Types of Intermolecular Forces
    •  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
  • Polymers and the Macromolecular Consequences of Intermolecular Forces
    •  describe the random coil conformation of a polymer, and calculate the random coil diameter and contour length of a vinyl (addition) polymer
    •  explain how entanglement and chain branching affects polymer properties
    •  give examples of natural addition and condensation polymers, and draw an amino acid and a peptide linkage
    •  explain primary, secondary, tertiary and quaternary structure in proteins
    •  recognise the types of intermolecular forces in natural and synthetic polymers
