Question

Expla Define Geometrical Isomerism ? Explain it with reference to square planner complexes of M2A2BC type.​

Answer 1

This type of isomerism is found in heteroleptic complexes due to different possible geometrical arrangements of the ligands. When two identical groups occupy adjacent positions, the isomer is called cis and when arranged opposite to one another, the isomer is called trans. e.g[Pt(NH3)2Cl2]
