Question

Match the complexes in the column I with coordination number in the column II.

Column I

Column II

Answer 1

In the complex ${\left[Co{\left(en\right)}_3\right]}^{2+}$, the coordination number of the metal is 6.
In the complex ${\left[Ca\left(EDTA\right)\right]}^{2-}$, the coordination numbrof the metal is 6.
In the complex, $\left[Ni{\left(CO\right)}_4\right]$ the coordination number of metal is 4.
In the complex, $\left[Ag{\left(N{H}_3\right)}_2\right]Cl$ the coordination number of metal is 2.
