Out of the following complex compounds, which of the compound will be having the minimum conductance

Question

Out of the following complex compounds, which of the compound will be having the minimum conductance in solution?
(A) $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right] \mathrm{Cl}_3$
(B) $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_5 \mathrm{Cl}\right] \mathrm{Cl}$
(C) $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_3 \mathrm{Cl}_3\right]$
(D) $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]$

Professor PC Thomas Classes · Answer

(c,d) : Conductance of complex compounds in solution depends on number of ions produced. As in both compounds (c) and (d), no ions will be produced, they will be having the minimum conductance in solution.
