Question

A coordination compound has the empirical formula $CoCl_3 \cdot 3NH_3$. What is its structural formula, and what will be its electrical conductivity in solution?

Answer: B

💡 Solution & Explanation

To satisfy the coordination number of 6 for $Co(III)$, all three $NH_3$ and all three $Cl^-$ must be inside the coordination sphere: $[Co(NH_3)_3Cl_3]$. It is a neutral complex and yields zero ions, hence zero electrical conductivity.
