As we have learned

Coordination number -

No. of ligands which are bounded directly to metal

 

- wherein

eg: \left [ Ni\left ( NH_{3} \right )_{4} \right ]^{2+}

Coordination No. \left ( CN \right )= 4

eg: \left [Co\left ( en\right )_{3} \right ]^{3+} 

Coordination No. \left ( CN \right )= 6

en is bidentate

en\rightarrow H_{2}N-CH_{2}-CH_{2}-NH_{2}

 

 According to modern view primary valency of complex compound is its oxidation number while secondary valency is the co-ordination number.

 

 

 

 

 


Option 1)

 Same as primary valency

Option 2)

  Sum of primary and secondary valencies

Option 3)

Same as secondary valency

Option 4)

None of these
