Question

Which of the characteristics is not common between ${\left[Cu(en{)}_2\right]}^{2+}$ and $\left[Ni(dmg{)}_2\right]?$

• A. Geometry of complexes
• B. Hybridisation of central metal cation
• C. Magnetic behaviour
• D. Number of stereoisomers

Answer 1

Answer: (C)

Geometry of complexes $\to$ Both square planar

Hybridisation of central metal cation $\to ds{p}^2$

Geometry of complexes $\to$ Both square planar Hybridisation of central metal cation $\to$ dsp ${}^2$ Magnetic behaviour ${\left[Cu(en{)}_2\right]}^{2+}\to$ Paramagnetic; $\left[Ni(dmg{)}_2\right]\to$
Diamagentic Number of stereoisomers $=0.$
