Co-Ordination Compounds Question 278
Question: Which one is the most likely structure of $ CrCl_3\text{,}6H_2O $ if 1/3 of total chlorine of the compound is precipitated by adding $ AgNO_3 $
Options:
A) $ CrCl_3.6H_2O $
B) $ [Cr{{( H_2O )}_3}Cl_3].{{( H_2O )}_3} $
C) $ [ CrCl_2{{( H_2O )}_4} ]Cl.2H_2O $
D) $ [CrCl{{(H_2O)}_5}]Cl_5.H_2O $
Show Answer
Answer:
Correct Answer: C
Solution:
The ions present in the ionisation sphere are precipited Hence $ [ CrCl_2{{( H_2O )}_4} ]Cl_2.H_2O $ contains 1/3 Cl in ionisation sphere to be precipited by $ AgNO_3 $ as $ AgCl $
