Which one of the following cyano complexes would exhibit the least value of paramagnetic behaviour?
Magnetic Moments (spin only) -
where n = number of the unpaired electron.
Number of unpaired electrons and corresponding magnetic moments
2
1
0
The magnetic moment of is the largest and equal to 3.8 BM while
is diamagnetic with no unpaired electrons.
Therefore, option (4) is correct.
