Chirality and achirality
WebChirality is the object’s inability to be superimposed on its mirror image and therefore, chiral objects are not superimposable on their mirror image. On the other hand, achiral objects are those objects that “are” … WebIn chemistry, a molecule or ion is called chiral (/ ˈ k aɪ r əl /) if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational …
