Question

Match the given pairs.

Answer 1

Two unupaired electrons are present in the complexes ${\left[Ni{\left(en\right)}_3\right]}^{2+}$ and ${\left[V{F}_6\right]}^{3-}$.
No unupaired electron is present in the complex ${\left[Fe{\left(CN\right)}_6\right]}^{4-}$.
Optical isomerism is shown by the complexes ${\left[Ni{\left(en\right)}_3\right]}^{2+}$ and ${\left[NiC{l}_2{\left(SCN\right)}_4\right]}^{4-}$.
Inner orbital complexes are ${\left[V{F}_6\right]}^{3-}$ and ${\left[Fe{\left(CN\right)}_6\right]}^{4-}$.
