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

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

(b)
$\lbrack MA_{5}B\rbrack$ due to absence of symmetry of ‘B ’ ligand cannot exist in the form of cis-trans isomer.
