Use the presence of a chiral centre to decide whether a molecule can rotate plane-polarised light, then describe the opposite rotations of pure optical isomers.
How this is tested
- Identify structures that can rotate plane-polarised light by locating a chiral centre.
- Distinguish pure enantiomers by opposite clockwise or anticlockwise optical rotation.
