All the following complex ions are found to be paramagnetic
The correct order of their paramagnetic moment (spin only) is
P > Q > R > S
P < Q < R < S
P = Q = R = S
P > R > Q > S
Both the ligands given here viz. and
are weak field ligands and are unable to cause pairing in their given complexes with the respective metal ions.
The electronic distribution in the central metal ion is given as
Hence, we can see that the paramagnetism follows the order
Therefore, option (1) is correct.
