25 A coordination compound $CrC{l}_{3}.4{H}_{2}0$ precipitates sitver chloride when

treated with silver nitrate. The molar conductance of its solution

corresponds to a total of two ions. Write structural formula of the

compound and name it.

Formation of white precipitate with AgNO, shows that atleast one CI ion is present outside

the coordination sphere, Moreover only two ions are obtained in solution, so only one Cl is

present outside the sphere.

Thus, the formula of the complex is $\left[Co{\left(H}_{}\right]$2O)4Cl2Cl2 and its IUPAC name is
