Assign the primary valence and secondary valence of the central metal in `[Ni(CO)_4]`.

Consider the coordination compound [Co(NH_3)_5Cl]Cl_2 what is the primary valence and secondary valence of the central metal ion in the above co ordination compound.

Consider the coordination compound [Co(NH_3)_5SO_4]Br .What is the primary valance and secondary valance of the central metal cobalt in the above coordination compound?

The charge on the central metal Ion In [Ni(CO)_4] Is

The primary and secondary valencies of the metal M in the complex [M(en)_(2)("ox")]NO_(2) are respectively ?

Coordination compounds contains central metal ion and ligands:- Primary valency of central metal in [Co(NH_3)_6]CI_3 is.

Primary valency of central metal atom/ion in [CO(NH_3)_6]Cl_3 is

Which of the following complexes are not correctly matched with the hybridisation of their central metal ion? (i) [Ni(CO)_4], sp^3 (ii) [Ni(CN)_4]^(2-), sp^3 (iii) [CoF_6]^(3-) , d^2 sp^3 (iv) [Fe(CN)_6]^(3-), sp^3 d^2 Select the correct answer using the codes given below:

Many theories have been put forth to explain the nature of bonding in co-ordination compounds:- On the basis of valence bond theory account for the diamagnetic behaviour of [Ni(CN)_4]^(2-) .
