Exam points

  • identify the same functional group and general formula as defining features of a homologous series
  • describe adjacent members as differing by a -CH2- unit in structural or molecular formulae
  • explain why similar functional groups give similar chemical properties while physical properties show trends
  • use tables of boiling points or formulae to predict the next member in a homologous series
