Find the number of complexes in which stability constant value is greater than the stability constant value of `[FeF_(6)]^(3-)`
`[Fe(CN)_(6)]^(3-)," "[Fe("ox")_(3)]^(3-),`
`[Fe(NH_(3))_(6)]^(3+)," "[Fe(H_(2)O)_(6)]^(3+),`
`[Fe(en)_(3)]^(3+)`

Text Solution

Verified by Experts

The correct Answer is:
5
All are more stable (because all have stronger ligands than `F^(-)`).
