"Strength of the ligand can affect the magnetic property of the coordination complex". á)Can you agree with this statement? b)illustrate the statement by taking two complexes.

Explanation

a. Yes
b. i. Tetracyảno nickelate
(I1) ion, .[Ni(CN)_4]^3 dot. Here .CN. - is a strong ligand. So electrons in .3 ~d. orbital are forced to pair, resulting in diamagnetism.

ii. Hexafiuoro cobaltate (III) ion, .[CoF_6]^2.. Here .F. - is a. weak ligand. So pairing of .3 ~d. electrons will not take place. So unpaired electrons are there and it gives paramagnetic behaviour.
