Question

A magnetic moment of 1.73 BM will be shown by one of the following compounds
​a) [Cu(NH₃)₄]²⁺
b) [Ni(CN)₄]^2-
c) TiCl₄
​d) [CoCl₆]^4-

Answer 1

Dear Student,

The element copper (Cu) in the complex represents the oxidation state of +1, expresses magnetic moment of 1.73 BM.
$$\begin{gathered} {\mu }_{eff}=\sqrt{n(n+2} \\ n\to No.ofunpairedelectron \end{gathered}$$

Hence the answer is Option (A) [Cu(NH₃)₄]²⁺
