Question

Oxidation state of central atom in Ni(CN)4 ²-​

Answer 1

Answer:

+2

>>>>Optical isomerism. Explain on the basis of valence bond theory that [Ni(CN)4]2– ion with square planar is diamagnetic and the [NiCl4]2– ion with tetrahedral geometry is paramagnetic. Ni is in the +2 oxidation state i.e., in d8 configuration. There are 4 CN− ions.
