Which of the following complexions is most stable ?

Answer»

`[Co(H_(2)O)_(6)]^(3+)`
`[CO(CN)_(6)]^(3-)`
`[CO(C_(2)O_(4))_(3)]^(3-)`
`[COF_(6)]^(3-)`

Solution :Stability of the complex ion depends upon the CHELATION. More is the number of chelating RINGS more will be the stability of complex ion. Among the given complex ion `C_(2)O_(4)^(2-)`is a bidentate LIGAND and thus forms chelation and will bemust stable .
`o X = C_(2) O_(4) [CO(C_(2)O_(4))_(3) ]^(2-)`
