Can achiral molecules have stereoisomers
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. Whether a molecule is chiral or achiral depends upon a … Artificially, it can be in the meso form (R,S), which is achiral.

WebTherefore it is impossible to tell a racemic mixture apart from an achiral substance using polarimetry alone. Note that the terms chiral and optically active should not be confused. It would be incorrect to say that a racemic … WebAchiral molecules usually contain a plane of symmetry but chiral molecules do not. What term specifically describes stereoisomers that are NOT mirror images of each other? Diastereomers 1) Nonsuperimposable upon its mirror image 2) Can be superimposed on its mirror image 1) chiral molecule 2) achiral molecule
