Optical Isomerism

  • Optical isomerism affects plane polarised light.
  • A chiral centre is a carbon atom with four different groups attached.
  • Enantiomers are mirror images that are non-superimposable.
  • A racemic mixture contains the two enantiomers in equal proportions.
  • When drawing enantiomers, start with the chiral centre and use a reflexion axis.
