Vedclass · Answer

(B) The magnetic moment is directly proportional to the number of unpaired electrons. The electronic configurations are:$Fe^{2+} ([Ar] 3d^6)$: $4$ unpaired electrons.$Fe^{3+} ([Ar] 3d^5)$: $5$ unpaired electrons.$Cr^{3+} ([Ar] 3d^3)$: $3$ unpaired electrons.$Mn^{3+} ([Ar] 3d^4)$: $4$ unpaired electrons.Since $Fe^{3+}$ has the maximum number of unpaired electrons $(5)$,it is the most paramagnetic.
