Which one of the following statement(s) is/are false ?

Options

A. Weak ligands like `F^(-),Cl^(-)" and "OH^(-)` usually form low spin complexes.
B. Strong ligand like `CN^(-)" and "NO_(2)^(-)`, generally form high spin complexes.
C. `[FeF_(6)]^(3-)` is high spin complex
D. `[Ni(CO)_(4)]` is high spin complex

Answer

A, B, D

Explanation

WFL form high spin, while, SFL form low spin complexes. `[Ni(CO)_(4)]` is diamagnetic.
