Question

Pick out the correct statement with respect to $\left[Mn\right(CN{)}_6{]}^{3-}$

• A. It is $s{p}^3{d}^2$ hybridised and octahedral
• B. It is $s{p}^3{d}^2$ hybridised and tetrahedral
  
• C. It is $d^{2}s{p}^3$ hybridised and octahedral
  
• D. It is $ds{p}^2$ hybridised and square planar

Answer 1

The correct option is C

It is $d^{2}s{p}^3$ hybridised and octahedral

$\left[Mn\right(CN{)}_6{]}^{3-}is{d}^{2}s{p}^3-$ hybridised and octahedral complex. In $\left[Mn\right(CN{)}_6{]}^{3-},$ Mn is in +3 oxidation state.
$M{n}^{3+}=3d^{4}4s^0$
