Question

Which one of the following complexes is not expected to exhibit isomerism?

• A. $\left[Ni\right(N{H}_3{)}_4(H_{2}O{)}_2{]}^{2+}$
• B. $\left[Pt\right(N{H}_3{)}_{2}C{l}_2]$
• C. $\left[Ni\right(N{H}_3{)}_{2}C{l}_2]$
• D. $\left[Ni\right(en{)}_3{]}^{2+}$

Answer 1

The correct option is C $\left[Ni\right(N{H}_3{)}_{2}C{l}_2]$

Compounds having tetrahedral geometry does not exhibit isomerism due to presence of symmetry elements. Here, $\left[Ni\right(N{H}_3{)}_{2}C{l}_2]$ has tetratedral geometry.
