Question

Which 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. [$Ni(en{)}_3{]}^{2+}$

Answer 1

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

[$Ni(N{H}_3{)}_{2}C{l}_2$] has tetrahedral geometry and thus, does not exhibit isomerism due to the presence of symmetry elements.

Hence, [$Ni(N{H}_3{)}_{2}C{l}_2$] is not expected to exhibit isomerism.
