Coordination Compounds 2 Question 40

####42. The compound having tetrahedral geometry is

(a) $\left[Ni(CN) _4\right]^{2-}$

(b) $\left[Pd(CN) _4\right]^{2}$

(c) $\left[PdCl _4\right]^{2-}$

(d) $\left[NiCl _4\right]^{2-}$

$(2004,1 M)$

Show Answer

Solution:

  1. $\left[NiCl _4\right]^{2-}: Ni^{2+}\left(3 d^{8}\right)$ Tetrahedral

In all other complexes, hybridisation at central metal is $d s p^{2}$ and complexes have square planar geometries.
