Answer
Conductance and Number of Ions in Solution
Conductance of a solution is directly proportional to the number of ions present in it.
Thus, compounds that produce the least number of ions will exhibit the minimum conductance.
Option 1 and Option 2 form an overall neutral complex in water, meaning:
- No counter-ions are released into the solution.
- The total ion concentration is extremely low.
Conclusion: Options 1 and 2 will show minimum conductance in solution due to the absence of free ions.
