Co-Ordination Compounds Question 240
Question: An aqueous solution of titanium chloride, when subjected to magnetic measurement, measured zero magnetic moment. Assuming the octahedral complex in aqueous solution, the formulae of the complex is:
Options:
A) $ [ Ti{{( H_2O )}_6} ]Cl_2 $
B) $ [ Ti{{( H_2O )}_6} ]Cl_4 $
C) $ [ TiCl_3{{( H_2O )}_3} ] $
D) $ [ TiCl_2{{( H_2O )}_4} ] $
Show Answer
Answer:
Correct Answer: B
Solution:
$ [ Ti{{( H_2O )}_6} ]Cl_4 $ Coordination number $ 6\Rightarrow $ octahedral complex Ti is in +4 oxidations state
$ \Rightarrow $ no unpaired electrons
$ \Rightarrow $ magnetic moment = 0 B.M.
