Transition and InnerTransition Elements - Result Question 92
####19. The geometries of the ammonia complexes of $Ni^{2+}, Pt^{2+}$ and $Zn^{2+}$, respectively, are
(2016 Main)
(a) octahedral, square planar and tetrahedral
(b) square planar, octahedral and tetrahedral
(c) tetrahedral, square planar and octahedral
(d) octahedral, tetrahedral and square planar
Show Answer
Solution:
- $\left[Ni\left(NH _3\right) _6\right]^{2+} s p^{3} d^{2}$ octahedral
$\left[Pt\left(NH _3\right) _4\right]^{2+} d s p^{2}$ square planar
$\left[Zn\left(NH _3\right) _4\right]^{2+} s p^{3}$ tetrahedral
