Arrange the following in the increasing order of number of unpaired electrons present in the central metal ion I. $\left[\mathrm{MnCl}_6\right]^{3-}$ II. $\left[\mathrm{Fe} \mathrm{F}_6\right]^{3-}$ III. $\left[\mathrm{Mn}(\mathrm{CN})_6\right]^{3-}$ IV. $\left[\mathrm{Fe}(\mathrm{CN})_6\right)^{3-}$
  1. IV $ \lt $ I $ \lt $ III $ \lt $ II
  2. $\mathrm{I} \lt \mathrm{III} \lt \mathrm{II} \lt \mathrm{IV}$
  3. IV $ \lt $ III $ \lt $ I $ \lt $ II
  4. I $ \lt $ II $ \lt $ III $ \lt $ IV

Solution


So order will be IV $ \lt $ III $ \lt $ I $ \lt $ II.
