[Cr(NH3)6]^(3+) is paramagnetic while [N...

`[Cr(NH_3)_6]^(3+)` is paramagnetic while `[Ni(CN)_4]^(2-)` is diamagnetic. Explain why?

Text Solution

Verified by Experts

The presence of three electron in `[Cr(NH_(3))_(6)]^(3+)` explains its paramagnetic character

`[Ni(CN)_(4)]^(2-)` is diamagnetic since there is no unpaired electrons.
