WebMay 10, 2015 · 11. Look for carbons with four different groups attached to identify potential chiral centers. Draw your molecule with wedges and dashes and then draw a mirror image of the molecule. If the molecule in the mirror image is the same molecule, it is achiral. If they are different molecules, then it is chiral. WebChiral molecules don’t have a plane of symmetry or a centre of symmetry. Chiral molecules exist in two stereoisomers, non-superimposable mirror images of each other, commonly known as enantiomers. Enantiomers are classified as “right-handed” or “left-handed” based on the absolute configuration.

WebApr 28, 2024 · An object that is chiral is an object that can not be superimposed on its mirror image. Chiral objects don't have a plane of symmetry. An achiral object has a plane of symmetry or a rotation-reflection axis, i.e. reflection gives a rotated version. Optical isomers or enantiomers are stereoisomers which exhibit chirality.
