A) 2
B) 3
C) 4
D) 5
Correct Answer: B
Solution :
Magnetic moment,\[{{\mu }_{eff}}=3.87\]BM corresponds to the number of unpaired electrons, n = 3 by applying the formula. \[{{\mu }_{eff}}=\sqrt{n\,(n+2)}BM\]for \[n=1,\] \[\mu =1.73\]BM; for \[n=2,\]\[\mu =2.83\]BM for \[n=3,\] \[\mu =3.87\]BM and so on.You need to login to perform this action.
