11.1 Homologous series

  • A homologous series is a set of compounds with one repeating functional group
Physical Properties of Alkanes
  • As chain length increases, so does boiling point, as an increased number of electrons causes stronger Van de Waal forces
  • The increase in boiling temperature is rapid at first, but flattens off


11.2 Hydrocarbons

  • Compounds containing only Hydrogen and carbon
  • Three examples,
    • Alkanes, Alkenes, Alkynes

Alkanes

  • Alkanes have a CH3 group at each end, and are made up of CH2 groups.
  • First five are,
    • Methane
    • Ethane
    • Propane
    • Butane
    • Pentane
