Question

Which one of the following octahedral complexes will not show geometric isomerism (A and B are monodentate ligands).

• A. $\lbrack MA_{5}B\rbrack$
• B. $\lbrack MA_{2}B_{4}\rbrack$
• C. $\lbrack MA_{3}B_{3}\rbrack$
• D. $\lbrack MA_{4}B_{2}\rbrack$

Answer 1

Answer: (A)

$\lbrack MA_{5}B\rbrack$

Answer 2

Octahedral complexes of the type

$\lbrack MA_{4}B_{2}\rbrack,\lbrack MA_{2}B_{4}\rbrack,\lbrack MA_{3}B_{3}\rbrack$ exhibit geometrical

isomerism.
