What is the magnetic moment of [Ni(CN)4]^-2​

Answer»

ong>Answer:

In presence of strong field CN- ions, all the ELECTRONS are paired up. The empty 4d, 3s and two 4p orbitals undergo dsp2 hybridization to make bonds with CN- ligands in square planar geometry. THUS [NI(CN)4]2- is diamagnetic. Since there is no any UNPAIRED electron therefore its magnetic moment is zero.

I hope it help you....
