Solution:

Geometry of complexes $ \rightarrow $ Both square planar

Hybridisation of central metal cation $ \rightarrow dsp^{2}$

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