(A)Square planer, paramagnetic
(B)Tetrahedral, diamagnetic
(C)Square planar, diamagneticCorrect
(D)Tetrahedral, paramagnetic

Answer: (C)

Solution

The ion is taken to be tetracyanonickelate(II), . Here has the configuration . is a strong-field ligand, so the two unpaired electrons pair up, leaving one orbital empty. This allows hybridisation (one , one , two
