Question

Calculate effective atomic number of copper in [cu(nh3)4]2+

Answer 1

effective atomic no. (EAN)

EAN= Z – x + 2nL

Z= Atomic number of the metal in the complex

x = Oxidation state of the metal in complex

n= Number of the ligands

L = Number of co-ordinate bonds formed by ligand

here,

z= 29

x=+2

n= 2

L= 2

EAN= 29-2+(2*2*2)

       = 27+8

       = 35

Answer 2

Effective atomic number = EAN= Z – x + 2nL

here,

z= 29

x=+2

n= 2

L= 2

EAN= 29-2+(2*2*2)

      = 27+8

     = 35
