WebDiastereomers are defined as compounds which have the same molecular formula and sequence of bonded elements but which are nonsuperimposable, non-mirror images. Enantiomers and diastereomers commonly called stereoisomers fall under the broader concept of isomerism which always involves the comparison of at least two species. Chirality is an asymmetric quality that is relevant in many fields of science. The word chirality comes from the Greek (kheir), which means “hand,” a common chiral item. A chiral item or system is distinct from its mirror image; that is, it cannot be overlaid onto it.

WebA chiral center is a carbon atom that is chiral at that point. If a molecule has even one chiral center, then it is a chiral molecule. But a molecule can have more than one chiral center, so we ... WebGenerally, Walden inversion is referred to as optical inversion. The inversion of configuration may or may not lead to the change in direction of rotation. Walden’s inversion is the reversal of a chiral centre in a molecule in a chemical reaction. Since the molecule can form two enantiomers around the chiral centre, the Walden inversion ...

WebOptical isomers are the stereoisomers that are nonsuperimposable mirror images of each other. and they differ in the direction in which they rotate plane-polarised light.They do not possess the plane of symmetry. The molecules which are non super-imposable mirror image of each other are called chiral and this property is called chirality.
