The Total solution for NCERT class 6-12
Amongst the following ions which one has thehighest magnetic moment value?
(i) [Cr(H2O)6]3+ (ii) [Fe(H2O)6]2+ (iii) [Zn(H2O)6]2+
(i) No. of unpaired electrons in [Cr(H2O)6]3+ =3
(ii) No. of unpaired electrons in [Fe(H2O)6]2+ =4
(iii) No. of unpaired electrons in [Zn(H2O)6]2+ =0
Hence,[Fe(H2O)6]2+ hasthe highest magnetic moment value.
