Exam points

  • define structural isomers by checking for the same molecular formula but different structural formulae
  • classify chain isomers from changes in the carbon skeleton and positional isomers from the location of a functional group or multiple bond
  • identify functional-group isomers when the same atom totals form different functional groups, using displayed or skeletal formulae
