Question

The geometries of the ammonia complexes of $N{i}^{2+},P{t}^{2+}$ and $Z{n}^{2+}$ , respectively, are

• A. octahedral, square planar and tetrahedral
• B. square planar, octahedral and tetrahedral
• C. tetrahedral, square planar and octahedral
• D. octahedral, tetrahedral and square planar

Answer 1

Answer: (A)

${\left[Ni{\left(N{H}_3\right)}_6\right]}^{2+}=$ octahedral

${\left[Pt{\left(N{H}_3\right)}_4\right]}^{2+}=$ square planar

${\left[Zn{\left(N{H}_3\right)}_4\right]}^{2+}=$ tetrahedral
