Which of the following statements is/are true for the complexes, [Fe(H_(2)O)_(6)]^(2+), [Fe(CN)_(6)]^(4-), [Fe(C_(2)O_(4))_(3)]^(2-)" and "[Fe(CO)_(5)] ?

Answer»

only `[FE(C_(2)O_(4))_(3)]^(3-)` shows optical isomerism.
`[Fe(C_(2)O_(4))_(3)]^(3-)` is less stable than `[Fe(CN)_(6)]^(4-)`.
All complexes have same effective atomic number.
`[Fe(CO)_(5)]` show back bonding.
