Question

The type of hybridisation and magnetic property of the complex $[MnC{l}_6{]}^{3-}$, respectively, are

• A. $d^{2}s{p}^3$ and diamagnetic
• B. $d^{2}s{p}^3$ and paramagnetic
• C. $s{p}^3{d}^2$ and paramagnetic
• D. $s{p}^3{d}^2$ and diamagnetic

Answer 1

The correct option is C $s{p}^3{d}^2$ and paramagnetic

$[MnC{l}_6{]}^{3-}\Rightarrow M{n}^{3+}$ with weak field ligand
$\Rightarrow$ high spin and outer orbital complex.

It has 4 unpaired electron.
Hence, it is $s{p}^3{d}^2$ with paramagnetic character.
