Question

6. Magnetic moment of ametal complex is 5.9 B M Number of
unpaired electrons in the complex is
a)2 b)3 c)4 d) 5
​

Answer 1

Answer:

Explanation:The oxidation state of Mn in [MnBr4]2− is +2 and since its magnetic moment is 5.92 BM This impliesn(n+2) = 5.92 BM, n=5. Hence Mn has 5 unpaired electrons.

Answer 2

electron in the complex is d) 5
