Question

Draw and discuss the structure of [Ni(CN)4]2 ion​

Answer 1

Answer:

Ni(CN)4]2- is a square planar geometry formed by dsp2 hybridisation and not tetrahedral by sp3. [Ni(CN)4]2- is diamagnetic, so Ni2+ ion has 3d8 outer configuration with two unpaired electrons. ... By this, there is no unpaired electron and the complex would be diamagnetic
