What did van't Hoff predict about allenes?
Their Color
Their Axial Chirality
Their Mass
Their Density
Answer
Axial chirality is a type of chirality that occurs when a molecule has a non-superimposable mirror image due to the restricted rotation around a double bond. Van't Hoff predicted that allenes, which have two double bonds connected by a single bond, would exhibit axial chirality. This prediction was later confirmed experimentally, and allenes are now known to be chiral molecules.
