Question

The given octahedral complexes have $d^{2}sp^{3 \, }or \, sp^{3}d^{2}$ hybridization, which one of the following will not show geometric isomerism ( if A and B are monodentate ligands)?

• A. $\left[\right.MA_{5}B\left]\right.$
• B. $\left[\right.MA_{3}B_{3}\left]\right.$
• C. $\left[\right.MA_{2}B_{4}\left]\right.$
• D. $\left[\right.MA_{4}B_{2}\left]\right.$

Answer 1

Answer: (A)

Octahedral complexes of the type $\left[\right.MA_{4}B_{2}\left]\right.,\left[\right.MA_{2}B_{4}\left]\right.,\left[\right.MA_{3}B_{3}\left]\right.$ exhibit geometrical isomerism , they can have identical ligands at cis/trans positions.
