WebIn chemistry, a molecule or ion is called chiral (/ ˈ k aɪ r əl /) if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes. This geometric property is called chirality (/ k aɪ ˈ r æ l ɪ t i /). The terms are derived from Ancient Greek χείρ (cheir) 'hand'; which is the canonical example of an … WebCorrect option is A) A chiral centre is an atom that has four different groups bonded to it in such a manner that it has a non superimposable mirror image.
