Vedclass · Answer

(C) The stability of coordination complexes is directly related to the Crystal Field Stabilization Energy $(CFSE)$ represented by $\Delta_o$.The $CFSE$ values for the given complexes are as follows:$I. \ [Mn(CN)_6]^{3-}$ ($Mn^{3+}$,$d^4$): $CFSE$ = $-1.6 \Delta_o$$II. \ [Co(CN)_6]^{4-}$ ($Co^{2+}$,$d^7$): $CFSE$ = $-1.8 \Delta_o$$IV. \ [Fe(CN)_6]^{3-}$ ($Fe^{3+}$,$d^5$): $CFSE$ = $-2.0 \Delta_o$$III. \ [Fe(CN)_6]^{4-}$ ($Fe^{2+}$,$d^6$): $CFSE$ = $-2.4 \Delta_o$Comparing the magnitudes of $CFSE$,the increasing order of stability is $I < II < IV < III$.

The correct increasing order of stability of the complexes based on $\Delta_o$ value is $:$
$I. \ [Mn(CN)_6]^{3-}$
$II. \ [Co(CN)_6]^{4-}$
$III. \ [Fe(CN)_6]^{4-}$
$IV. \ [Fe(CN)_6]^{3-}$
