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

  1. \( \mathrm{[Co(NH_3)_3 Cl_3]} \)
  2. \( \mathrm{[Co(NH_3)_4 Cl_2]} \)
  3. \( \mathrm{[Co(NH_3)_6]Cl_3} \)
  4. \( \mathrm{[Co(NH_3)_5 Cl]Cl} \)

Correct answer · Option 1

\( \mathrm{[Co(NH_3)_3 Cl_3]} \)

Explanation

Conductance depends on the number of ions produced in solution. \( \mathrm{[Co(NH_3)_3 Cl_3]} \) is a non-electrolyte yielding 0 ions, hence minimum conductance.
