The question is incomplete as the options have not been given to choose from. So, I am going to give the answer based on a similar common question found on other sites.
The question is - 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⁺
Solution - Magnetic moment (μ) = √n (n + 2), where n = no. of unpaired electrons.
The no. of unpaired electrons in [Cr(H₂O)₆]³⁺ = 3. So, the magnetic moment = √3 (3 + 2) = √15
The no. of unpaired electrons in [Fe(H₂O)₆]²⁺ = 4. So, the magnetic moment = √2 (4 + 2) = √24
The no. of unpaired electrons in [Zn(H₂O)₆]²⁺ = 0. So, the magnetic moment = 0.
Therefore, the highest magnetic moment is present for the ion [Fe(H₂O)₆]²⁺.
