Question

$\left[Fe\right(H_{2}O{)}_6{]}^{3\oplus }$ has a magnetic moment of 5.92 BM. Thus hybridization of Fe is

• A. $d^{2}s{p}^3$
• B. $s{p}^3{d}^2$
• C. $ds{p}^2$
• D. $s{p}^3$

Answer 1

The correct option is B $s{p}^3{d}^2$

As per VBT, the complex is $s{p}^3{d}^2$ hybridized. Use formula : $\mu =\sqrt{n(n+2)}$
