Q. One of the following complexes shows geometrical isomerism. The complex is
Solution:
Heteroleptic complexes with coordination numbers and show this type of isomerism. It arises due to the difference in the geometrical arrangement of the ligands around the central metal ion. When same ligands occupies the adjacent position in the polyhedra are known as cis-isomers, whereas when same ligands occupy the opposite position in the polyhedra are known as trans-isomers.
(Geometrical isomers of
