WebApr 26, 2024 · The word Chiral is derived from Greek word 'KHEIR' or 'CHEIR' which means hand.1,8-10 Chirality is a property of a molecule wherein the mirror images do not superimpose on each other owing to the difference in spatial arrangement of the atoms in the molecule (Figure 1).1 WebChiral centers. An atom with four different groups bonded to it in such a way that it has a non-superimposable mirror image is called a chiral center. "The objects which are non-superimposable on their mirror image are said to be chiral and this property is known as chirality''. An example of chirality is a pair of hands. http://ursula.chem.yale.edu/~chem220/chem220js/STUDYAIDS/isomers/RS14272/planar.html install error - 0x8000ffff windows 10
