Chirality without Asymmetric Centres

Use the mouse and Right-click (Windows) or Command-click (Mac OS) to modify the models.

These two allenes are enantiomers. Try and manipulate the models to convince yourself that they are different.

 

Biphenyls can be resolved if they have ortho substituents. Is this the correct enantiomer?

 

Binaphthol and BINAP can also be resolved and are important ligands in enantioselective catalysis.

 

Hexahelicene is a Curiosity! It has a massive rotation.
