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}

 

 

 

K_{3}[AI(C_{2}O_{4})_{3}]             C_{2}O^{2-}_{4}\rightarrow Bidentate ligand

C\cdot N=3\times 2=6

[Co(en)_{2}Cl]Cl

en\rightarrow Bidentate ligand 

Cl\rightarrow\textup{ form one bond}

C\cdot N=2\times 2+1=5

Answer is (5 & 6)

 


Option 1)

5 and 3

Option 2)

3 and 3

Option 3)

6 and 6

Option 4)
