Where two or more than two complexes having similar molecular weight (or) molecular formula but their structural arrangements are different these forms are known as isomer & this phenomenon is known as isomerism; isomerism are of two types structural & stereoisomerism ; stereoisomerism are of two types geometrical isomerism & optical isomerism; compound which has plane of symmetry will not exhibit optical isomerism.
Total number of stereoisomers possible for complex [M(AB)bcde].
Answer:
Solution:
The complex [M(AB)bcde] has a bidentate ligand (AB) and four different monodentate ligands (b, c, d, e). This is an octahedral complex.
The number of stereoisomers for an octahedral complex of the type [M(AB)bcde] is given by .
However, if the bidentate ligand AB is symmetrical (e.g., ethylenediamine, 'en'), then the number of stereoisomers is .
Assuming AB is a symmetrical bidentate ligand, the total number of stereoisomers is .
