What can be inferred from the magnetic moment values of the following complex species?Example Magnetic Moment (BM)K4[Mn(CN)6] 2.2[Fe(H2O)6]2+ 5.3K2[MnCl4] 5.9

Amongst the following ions? Which one has the highest magnetic moment value:

A four-coordinate complex of Co2+ labelled A has a spin-only magnetic momentof 3.87 BM. Another four-coordinate complex of Co2+ labelled B has a spin-only magnetic moment 0f 1.73 BM. Use the magnetic moments to deduce thegeometries of complexes A and B

Amongst the following ions? Which one has the highest magnetic moment value: (i) [Cr(H2O)6]3+ (ii) [Fe(H2O)6]2+ (iii) [Zn(H2O)6]2+

The pair in which both the species have same magnetic moment (spin only) is.A     [𝐶𝑜𝐶𝑙4]2−,  [𝐹𝑒(𝐻2𝑂)6]2−B     [𝑀𝑛(𝐻2𝑂)6]2+ , [𝐶𝑟(𝐻2𝑂)6]2+C     [𝐶𝑟(𝐻2𝑂)6]2+, [𝐹𝑒(𝐻2𝑂)6]2+D
