Which of the following is inner orbital complex as well as diamagnetic in nature ?

Options

A. `[Cr(NH_(3))_(6)]^(3+)`
B. `MnO_(4)^(2-)`
C. `[Fe(EDTA)]^(-)`
D. `[Co(H_(2)O)_(6)]^(3+)`

Answer

D

Explanation

`{:((a)[Cr(NH_(3))_(6)]^(3+),"Inner orbital"," Paramagnetic"),((b)[MnO_(4)]^(2-),"Inner orbital"," Paramagnetic"),((c)[Fe(EDTA)]^(-),"Inner orbital"," Paramagnetic"),((e )[Co(H_(2)O)_(6)]^(3+),"Inner orbital"," Diamagnetic"):}`
