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)` .
