Chiral molecules are non-superimposable mirror images of each other and exist as enantiomers.
WebChirality (chemistry) The term chiral (pronounced /ˈkaɪɹ (ə)l̩/) is used to describe an object that is non-superimposable on its mirror image. Human hands are perhaps the most … WebAbsolute configuration refers to the spatial arrangement of atoms within a chiral molecular entity (or group) and its resultant stereochemical description. [1] Absolute configuration is typically relevant in organic molecules, where carbon is bonded to four different substituents. This type of construction creates two possible enantiomers.
In chemistry, a molecule or ion is called chiral 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 (/kaɪˈrælɪti/).
