Question

The magnetic moment of complex Kn [MnF6] is 4.9 BM. What is the oxidation number of Mn and what is the value of n? (A)  M ( V), n=1  (B)  Mn (II), n=4  (C)  M (III), n=3  (D)  Mn (IV), n=2

In Kn [MnF6] is n = 3 because the magnetic moment of Mn3+ is 4.9 2√S(S+1)=2 √2(2+1)=4.9 n=2

Q. The magnetic moment of complex $K n [M n F_{6}]$ is 4.9 BM. What is the oxidation number of Mn and what is the value of n?

$M (V), n = 1$

$M n (II), n = 4$

$M (III), n = 3$

$M n (I V), n = 2$

In $K n [M n F_{6}]$ is n = 3 because the magnetic moment of $M n^{3 +}$ is 4.9 $2 S (S + 1) = 2 2 (2 + 1) = 4.9$ $n = 2$
