WebThese types of isomers have the same constitutions, but different geometric arrangements of atoms. Stereoisomers can be broadly classified into two types, namely enantiomers and diastereomers. 1. Enantiomers. … WebChirality and Symmetry. All objects may be classified with respect to a property we call chirality (from the Greek cheir meaning hand). A chiral object is not identical in all respects (i.e. superimposable) with its mirror image. An achiral object is identical with (superimposable on) its mirror image. Chiral objects have a "handedness", for example, …
