The complex thai has highest cry splitting energy

Question:

The complex thai has highest cry splitting energy $(\Delta)$, is :

  1. $\mathrm{K}_{3}\left[\mathrm{Co}(\mathrm{CN})_{6}\right]$

  2. $\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{5}\left(\mathrm{H}_{2} \mathrm{O}\right)\right] \mathrm{Cl}_{3}$

  3. $\mathrm{K}_{2}\left[\mathrm{CoCl}_{4}\right]$

  4. $\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{5} \mathrm{Cl}\right] \mathrm{Cl}_{2}$

Correct Option: 1

Solution:

As complex $\mathrm{K}_{3}\left[\mathrm{Co}(\mathrm{CN})_{6}\right]$ have $\mathrm{CN}^{-}$ligand which is strongfield ligand amongst the given ligands in other complexes.
