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)

octahedral, square planar and tetrahedral

The complex of $N{i}^{2+},P{t}^{2+}andZ{n}^{2+}$ with $N{H}_3$ are $\left[Ni\right(N{H}_3{)}_6{]}^{2+}$,$\left[Pt\right(N{H}_3{)}_4{]}^{2+}$ inner orbital, and $\left[Zn\right(N{H}_3{)}_4{]}^{2+}$ outer orbital complex. Hence the the geometries are octahedral,square planar and tetrahedral respectively. hence the correct option is A.
