Coordination Compounds - Result Question 18
####20. Which one of the following octahedral complexes will not show geometric isomerism? ( $A$ and $B$ are monodentate ligands)
[2003]
(a) $[MA_5 B]$
(b) $[MA_2 B_4]$
(c) $[MA_3 B_3]$
(d) $[MA_4 B_2]$
Show Answer
Solution:
(a) $MA_3 B_3-2$ geometrical isomers
$MA_2 B_4-2$ geometrical isomers
$MA_4 B_2-2$ geometrical isomers
The complexes of general formula $Ma_6$ and $Ma_5 b$ octahedral geometry do not show geometrical isomerism.
