Spin only magnetic moment in BM of
Question:

Spin only magnetic moment in BM of

$\left[\mathrm{Fe}(\mathrm{CO})_{4}\left(\mathrm{C}_{2} \mathrm{O}_{4}\right)\right]^{+}$is :

 

  1. $5.92$

  2. 0

  3. 1

  4. $1.73$


Correct Option: , 4

Solution:

$\left[\mathrm{Fe}(\mathrm{CO})_{4}\left(\mathrm{C}_{2} \mathrm{O}_{4}\right)\right]^{+}$

One unpaired electron

Spin only magnetic moment

$=\sqrt{3} \mathrm{~B} \cdot \mathrm{M} .=1.73 \mathrm{BM}$
