Question

The correct increasing order of stability of the complexes based on ${\Delta _0}$ value is :
I. ${\left[ {{\rm{Mn}}{{({\rm{CN}})}_6}} \right]^{3 - }}$
II. ${\left[ {{\rm{Co}}{{({\rm{CN}})}_6}} \right]^{4 - }}$
III.${\left[ {{\rm{Fe}}{{({\rm{CN}})}_6}} \right]^{4 - }}$
IV. ${\left[ {{\rm{Fe}}{{({\rm{CN}})}_6}} \right]^{3 - }}$

Select the correct option:

III < II < IV < I

${\rm{I}} < {\rm{II}} < {\rm{IV}} < {\rm{III}}$

IV < III < II < I

II < III < I < IV
