If all the groups attached to the central carbon atom are not completely different, then there exists a plane of symmetry. Such molecules are known as achiral molecules. It is also clear that only the molecule having a chiral centre will exhibit optical isomerism, which is shown below.
WebWhile optical activity occurs in structures that are chiral in three dimensions (such as helices), the concept of chirality can also be applied in two dimensions. 2D-chiral patterns, such as flat spirals, cannot be superimposed with their mirror image by translation or rotation in two-dimensional space (a plane). 2D chirality is associated with … WebBy taking chiral Ag 14 (SPh(CF 3) 2) 12 (PPh 3) 4 (DMF) 4 (Ag 14) clusters with bulky thiolate ligands as an example, we demonstrate herein an interesting assembly disassembly …
