Which of the following pairs of ions will have same spin only magnetic moment values within the pair?
A. $\mathrm{Zn}^{2+}, \mathrm{Ti}^{2+}$
B. $\mathrm{Cr}^{2+}, \mathrm{Fe}^{2+}$
C. $\mathrm{Ti}^{3+}, \mathrm{Cu}^{2+}$
D. $\mathrm{V}^{2+}, \mathrm{Cu}^{+}$
Choose the correct answer from the options given below
C and D only
A and D only
A and B only
B and C only
Solution
Magnetic moment $\mu=\sqrt{n(n+2)} B M$
$\mathrm{n} \Rightarrow$ Number of unpaired electrons
Hence $\left(\mathrm{Cr}^{2+}, \mathrm{Fe}^{2+}\right)$ and $\left(\mathrm{Ti}^{3+}, \mathrm{Cu}^{2+}\right)$ are the pair of same magnetic moment.
