Q.
Three arrangements are shown for the complex, $[Co(en) (NH_{3})_{2}Br_{2}]^{+}$. Which one is the wrong statement?
Coordination Compounds
Solution:
I and II are geometrical isomers.
I is cis as two $Br$ atoms are adjacent to each other.
II is trans as two $Br$ atoms are opposite to each other.
II and III are geometrical isomers.
II is trans as two $Br$ atoms are opposite to each other.
III is cis as two $Br$ atoms are adjacent to each other.
I and III are optical isomers.
They are non-superimposable mirror images of each other.
