Question

Which one of the following octahedral complexes does not show geometric isomeism? (A and B are monodentate ligands)

• A. $\left[M{A}_2{B}_4\right]$
• B. $\left[M{A}_3{B}_3\right]$
• C. $\left[M{A}_4{B}_2\right]$
• D. $\left[M{A}_{5}B\right]$

Answer 1

The correct option is D $\left[M{A}_{5}B\right]$

$\left[M{A}_{5}B\right]$ doesn't show geometric isomerism as it is symmetric.
