Two Stereocentres

Enantiomers and diastereomers

An interactive lesson with 5 steps, about 5 minutes: you predict, drag and solve, with instant feedback on every answer. It runs in your browser and needs JavaScript.

What you’ll learn

• Up to 2ⁿ stereoisomers for n centres.
• Enantiomers: all centres inverted (mirror images). Diastereomers: some inverted.
• Meso compounds have stereocentres but a mirror plane: achiral.

Steps

1. More centres, more isomers
2. Three centres
3. Name the relationship
4. Meso: a hidden mirror
5. Separating them
