Concept explainers
a)
Interpretation: Draw the geometric isomers structures for the given complex ion.
Concept Introduction:
Geometry of coordination compounds: The study of geometry of the coordination compound helps in understanding the physical and chemical property of the compound.
Stereoisomer: The same molecular formula but different with the arrangements of atoms around the metal ion. The Ligands are arranged differently in coordination compounds.
Geometric isomers: stereoisomers that cannot be interconverted without breaking the
Optical isomers: Optical isomers are non-superimposable mirror images.
Plane-polarized light: Light that oscillates in a single plane.
To Identify: Geometric isomers for the given complex ion to be drawn.
