Edexcel IAL Chemistry A2 15.4 Racemic mixture
Look for a 50:50 mixture of enantiomers or equal attack on both faces of a planar carbonyl, then link the sample to no net optical activity.
How this is tested
- State that a racemic mixture contains equal amounts of the two enantiomers.
- Explain no optical activity by equal and opposite rotations cancelling in the sample.
- Recognise enantiomer pairs that can form a racemic mixture when combined.
