If Ni 2 + is replaced by Pt 2 + in the complex NiCl 2 Br 2 2 - , which of the following properties are expected to get changed? A. Geometry B. Geometrical isomerism C. Optical isomerism D. Magnetic properties
Options
- AA and D
- BA, B and C
- CB and C
- DA, B and D
Correct answer
D. A, B and D
Step-by-step solution
When Ni 2 + is replaced by Pt 2 + in the complex NiCl 2 Br 2 2 - , the following properties are expected to be changed: A. Geometry: Since Pt 2 + and Ni 2 + have different coordination preferences and atomic sizes, the replacement is likely to result in a change in the geometry of the complex. That is it changes to square planar. B. Geometrical isomerism: If the replacement of Ni 2 + with Pt 2 + leads to a change in the ligand arrangement, it can result in the generation of cis and trans isomers. C. Magnetic proper
