WebJul 3, 2024 · Chirality: Chiral & Achiral Objects. Chirality is an intrinsic property of a 3-dimensional object. An object is either chiral, or it is not--no in-between. The simple test for chirality is to see whether the mirror image of an object is superimposable (identical): if it is, the object is not chiral (we call this achiral); if the mirror image is ...
