The type of hybridization and the magnetic property of [MnCl_6]^ 3-...

The type of hybridization and the magnetic property of [MnCl6]3−\left[\mathrm{MnCl}_6\right]^{3-} are :

Options

  1. Ad2sp3d^2 s p^3, paramagnetic with four unpaired electrons
  2. Bsp3 d2\mathrm{sp}^3 \mathrm{~d}^2, paramagnetic with four unpaired electrons
  3. Cd2sp3\mathrm{d}^2 \mathrm{sp}^3, paramagnetic with two unpaired electrons
  4. Dsp3 d2\mathrm{sp}^3 \mathrm{~d}^2, paramagnetic with two unpaired electrons

Correct answer

B. sp3 d2\mathrm{sp}^3 \mathrm{~d}^2, paramagnetic with four unpaired electrons

Step-by-step solution

[MnCl6]3− contains Mn+3Mn+3:−[Ar]3d4 Ligand ⇒Cl−(WFL)\begin{aligned} & {\left[\mathrm{MnCl}_6\right]^{3-} \text{ contains } \mathrm{Mn}^{+3}} \\ & \mathrm{Mn}^{+3}:-[\mathrm{Ar}] 3 \mathrm{ d}^4 \\ & \text{ Ligand } \Rightarrow \mathrm{Cl}^{-}(\mathrm{WFL})\end{aligned}\text{ Hybridisation }=\mathrm{sp}^3 \mathrm{ d}^2 4 unpaired electrons$
