WebHow do you find chirality centers? Answer: Chirality means a molecule that is mirrored won't be superimposable. Explanation: A chiral molecule can usually be found if there is no plane of symmetry, an example in every day life of this is your hands. (They are mirror images but one can't be put onto the other such that they would appear the same). WebA chiral molecule is non-superimposable with its mirror image, and has a "handedness" (think of shoes, which specifically go with a right or left foot). An achiral molecule is superimposable with its mirror image and do not have "handedness" (think of a baseball bat, which can be used with either hand).. Created by Jay. Sort by: Top Voted
