WebChirality 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). Picture of chiral hands: WebA chiral center is a carbon atom that is chiral at that point.
