Concept of "non-superimposable mirror image" in chirality

WebThe definition of chirality is the property of any object (molecule) being non-superimposable on its mirror image. The left and right hand are mirror images of each other, and they are not superimposable, so both the left hand and right hand are chiral. You can also find many other objects in daily life that show chirality as well. WebChiral definition, (of a molecule) not superimposable on its mirror image. See more. citics securities hk
