Question
The diamagnetic species is :
Options
A.[Ni(CN4)]2-
B.[NiCl4]2-
C.[NoCl4]2-
D.[NoF6]2-
Solution
In [Ni(CN4)]2-, nickel has oxidation no. of +2. So electronic configuration of its outer most orbital is as follows :
However,CN- is a strong ligand which forces the electron to pair up. Thus two unpaired electron are forced to pair up by CN-
So, it becomes diamagnetic.
