Match the metal ions given in column I with the spin magnetic moments of the ions given in column II and assign the correct code

 Column I Column II
1.Co3+i.8 BM
2.Cr3+ii.35 BM
3.Fe3+iii.3 BM
4.Ni2+iv.24 BM
  v.15 BM

Options:

Answer:
C
Solution:

Usingμ=n(n+2)
Co3+=[Ar]3d6,unpairede-(n)=4
Spin magnetic moment=4(4+2)=24 BM
Cr3+=[Ar]3d3,unpairede-(n)=3
Spin magnetic moment=3(3+2)=15 BM
Fe3+=[Ar]3d5,unpairede-(n)=5
Spin magnetic moment=5(5+2)=35 BM
Ni2+=[Ar]3d8,unpairede-(n)=2
Spin magnetic moment=2(2+2)=8 BM
