WebChirality / k aɪ ˈ r æ l ɪ t iː / is a property of asymmetry important in several branches of science. The word chirality is derived from the Greek χειρ (kheir), "hand", a familiar chiral object.. An object or a system is chiral if it is distinguishable from its mirror image; that is, it cannot be superimposed onto it. Conversely, a mirror image of an achiral object, such as … http://www1.lasalle.edu/~price/Chapter%2005%20Wade%208th.ppt
Webchirality in organic molecules is a tetrahedral atom, most commonly carbon, bonded to four different groups. A carbon with four different groups bonded to it is called a chiral center. … WebJan 23, 2024 · Chirality. Chirality essentially means 'mirror-image, non-superimposable molecules', and to say that a molecule is chiral is to say that its mirror image (it must have one) is not the same as it self. …
