Co-Ordination Compounds Question 112
Question: Which would exhibit ionisation isomerism
[MP PET 1997]
Options:
A) $ [ Cr{{( NH_3 )}_6} ]Cl_3 $
B) $ [ Co{{( NH_3 )}_5}Br ]SO_4 $
C) $ [ Cr{{(en)}_2}Cl_2 ] $
D) $ [ Cr{{(en)}_3}Cl_3 ] $
Show Answer
Answer:
Correct Answer: B
Solution:
The compound which has same composition but give different ions in solution, show ionization.
So $ [Co{{(NH_3)}_5}Br] $
$ SO_4^{{}} $ is ionization isomer.
$ [Co{{(NH_3)}_5}Br]SO_4 $ ⇌ $ {{[Co{{(NH_3)}_5}Br]}^{2+}}+SO_4^{2-} $
$ [Co{{(NH_3)}_5}SO_4]Br $ ⇌ $ {{[Co(NH_3)SO_4]}^{+}}+B{r^{-}} $ .
