Edexcel IAL Chemistry A2 15.2 Optical isomerism and chiral centres
Check whether one carbon is bonded to four different groups, then use wedge and dashed bonds or mirror-image drawings to show the stereochemical relationship.
How this is tested
- Mark or count chiral centres in displayed, skeletal, amino acid or medicine structures.
- Explain optical isomerism through non-superimposable mirror-image enantiomers.
- Draw 3D enantiomer diagrams with wedges, dashed bonds and a true mirror relationship.
