"WebA substance will have a point chirality if a chiral center gets coincided with an atom. For an organic compound, the asymmetric carbon is often called stereocenter. If a molecule has an even number of stereocenters, then there can be one or more stereocenter/s which will not be chiral. Chirality is a very important concept for biochemistry as well.
