Amongst the following ions which one has the highest magnetic moment value? (i) [Cr(H 2 ​ O) 6 ​ ] 3+ (ii) [Fe(H 2 ​ O) 6 ​ ] 2+ (iii) [Zn(H 2 ​ O) 6 ​ ] 2+

Text Solution

Verified by Experts

[Fe(H, O)_6]^2+. All are octahedral, ỏuter orbital and high.spincomplexes. .Cr^3+: 3 ~d^3. .Fe^2+: 3 ~d^6. .Zn^2+: 3 ~d^10. .Cr^3+. has 3 unpaired electrons, .Zn^2 *. does.not haye unpaired electrons, .Fe^2+. has 4 unpaired electrons. .therefore[Fe(H, O)_4]^3 *. has highest magnetic moment.
