Which of the following order of stability of complex ion is Incorrect ?

Answer»

`[Fe(C_2 O_4)_3]^(3-) lt [Fe(H_2 O)_6]^(3+)`
`[Fe ("EDTA)]^(-) gt [Fe(H_2 O)_6]^(3+)`
`[Ni(en)_2 ]^(2+) gt [Ni(DMG)_2]`
`[Fe(CN)_6]^(3-) gt [Fe(CN)_6]^(4-)`

Solution :`[Co(NH_3)_6]Cl_3 OVERSET(AgNO_3)to `3 mole of AGCL
`[Co(NH_3)_5 Cl]Cl_2 overset(AgNO_3)to ` 2 mole of AgCl
`[Co(NH_3)_4 Cl_2] Cl overset(AgNO_3)to ` 1 mole of AgCl
Complexes are respectively `[Co(NH_3)_6 Cl_3,[Co(NH_3)_5 Cl]Cl_2 and [Co(NH_3)_4 Cl_2]Cl`
