What is the spin only magnetic moment (in B.M. unit) of complex $[Cu (NH_{3})_{4}] SO_{4}$

Answer:

1.73

Solution:

The oxidation state of Cu is +2. The electronic configuration of Cu²⁺ is $[A r] 3 d^{9}$ . It has one unpaired electron.

Spin only magnetic moment $μ = n (n + 2)$ B.M.

Here $n = 1$ .

$μ = 1 (1 + 2) = 3 = 1.73$ B.M.
