Which one of the cyano complexes would exhibit the lowest value of para magnetic behaviour ?
(At. No. Cr = 24, Mn = 25, Fe = 26, Co = 27)

A

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

B

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

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
B
For `Fe^(+3) and Mn^(+2) to n=5`
