Exam points

  • define stereoisomers as molecules with the same structural formula but different three-dimensional arrangements
  • identify geometrical (cis/trans) isomerism from restricted rotation about C=C and two different groups on each double-bonded carbon
  • identify optical isomerism from a chiral centre and represent non-superimposable mirror-image molecules
