Question

Structural formula of tetraaquadichloridochromium(III) chloride

• A. $\left[\left( H _{2} O \right)_{4} Cl _{2} Cr \right] Cl _{2}$
• B. $\left[ Cl _{2}\left( H _{2} O \right)_{4} Cr \right] Cl _{3}$
• C. $\left[ Cr \left( H _{2} O \right)_{4} Cl _{2}\right] Cl$
• D. $\left[ Cr \left( H _{2} O \right)_{4} Cl _{3}\right]$

Answer 1

Answer: (C)

Tetraaquadichloridochromium(III) chloride
$\Rightarrow 4 H _{2} O , 2 Cl ^{-}$in secondary valency and $1\,\, Cl ^{-}$in primary valency
$\Rightarrow \left[ CrCl _{2}\left( H _{2} O \right)_{4}\right] Cl$
