Text Solution

AI Generated Solution

To understand why geometrical isomerism is not possible in tetrahedral complexes with two different types of unidentate ligands coordinated with a central metal ion, we can follow these steps: ### Step-by-Step Solution: 1. **Definition of Tetrahedral Complexes**: Tetrahedral complexes have a central metal atom surrounded by four ligands positioned at the corners of a tetrahedron. The bond angles between the ligands are approximately 109.5°. 2. **Types of Ligands**: ...

    Geometrical isomerism arises in heteroleptic complexes due to different possible geometrical arrangement of the ligands. Important examples of this behaviour are found with coordination number 4 and 6. Such isomerism is not possible for a tetrahedral geometry but it is possible for square planar as well as octahedral complexes. Optical square planar as well as octahedral complexes. Optical square planar as well as octahedral complexes. Optical isomers are mirror images that cannot be superimposed on one another. These are called enantiomers. Optical isomerism is common in octahedral complexes involving bedentate ligands. Which of the following complexes will show geometrical isomerism ?
