Q. The $\Delta_{t}$ of the following complexes follows the order
(I) $\left[ CoCl _{4}\right]^{2-}$
(II) $\left[ CoBr _{4}\right]^{2-}$
(III) $\left[ Co ( NCS )_{4}\right]^{2-}$

Coordination Compounds

Solution:

The order of CFSE for tetrahedral complexes$ [CoCl_{4}]^{2-}< \left[CoBr_{4}\right]^{2-}< \left[ Co ( NCS )_{4}\right]^{2-}$
