Question

A coordination compound CrCl3 ⋅ 4H2O gives white precipitate of AgCl with AgNO3. The molar conductance of the compound corresponds to two ions. The structural formula of the compound is (A) [Cr(H2O )4Cl3] (B) [Cr(H2O )3Cl3]H2O (C) [Cr(H2O)4Cl2]Cl (D) [Cr(H2O )4Cl]Cl2

It gives precipitate with AgNO3 it means it gives Cl- ions in the solution. Since conductivity corresponds to two ions, it shows one Cl- is outside the coordination sphere. The structure will be [Cr(H2O)4Cl2] Cl → [Cr(H2O)4Cl2]++Cl- AgNO3+Cl- → underset textwhite ppt.Agcl+NO-3

Q. A coordination compound $C r C l_{3} \cdot 4 H_{2} O$ gives white precipitate of $A g Cl$ with $A g N O_{3}$ . The molar conductance of the compound corresponds to two ions. The structural formula of the compound is

$[C r (H_{2} O)_{4} C l_{3}]$

$[C r (H_{2} O)_{3} C l_{3}] H_{2} O$

$[C r (H_{2} O)_{4} C l_{2}] Cl$

$[C r (H_{2} O)_{4} Cl] C l_{2}$
