Question

For the $t_{2g}^6{e}_g^2$ system, the value of magnetic moment $\left(\mu \right)$ is:

• A. $2.83BM$
• B. $1.73BM$
• C. $3.87BM$
• D. $4.92BM$

Answer 1

Answer: (A)

$2.83BM$

$M=\sqrt{n(n+2)}$

where, n= no. of unpaired $e^{-}$

Here, $n=2$

$\therefore M=\sqrt{2(2+2)}$

$\Rightarrow \sqrt{8}=2.82BM$

Hence, option A is correct.
