The complex which has no d-electron in the central metal atom is .

A

`[MnO_(4)]^(Θ)`

B

`[Co(NH_(3))_(6)]^(3+)`

C

`[Fe(CN)_(6)]^(3-)`

D

`[Cr(H_(2)O)_(6)]^(3+)`

Text Solution

Verified by Experts

The correct Answer is:
a
`MnO_(4)^(Θ):Mn(+7),Mn(Z =25)implies 3d^(5) 4s^(2)`
No d - electrons left . `Mn^(+7) =3d^(0)` .

According to C.F.T, attraction between the central metal ion and ligands in a complex is purely electrostatic. The transition metal which forms the central atom cation in the complex is regarded as a positive ion. It is surrounded by negative ligands or neutral molecules which have a lone apir of electrons, if the ligand is a neutral molecule such as NH_(3) , the negative and of the dipole in the molecule is directed towards the metal cation. the electrons on the central metal ion are under repulsive forces from those on the ligands. thus the electrons occupy the d-orbitals remain away from the direction of approach ligands. ltBrgt Q.
