Out of the following complex compounds, which of the compound will be having the minimum conductance in solution?
Show answer and solution
Sol. Conductance of any complex depends on the following factor.
(1) Number of ions produced by complex.
(2) If number of ions are same then we will check charge on complex unit.
(1) [Co⁺³(NH₃)₃Cl₃]
(2) [Co⁺²(NH₃)₄Cl₂] Both complex units have no charge. Therefore both complex units have same conductance.
(3) [Co(NH₃)₆]Cl₃ → [Co(NH₃)₆]⁺³ + 3Cl⁻
(4) [Co(NH₃)₅Cl]Cl → [Co(NH₃)₅Cl]⁺ + Cl⁻
