Question

From the following which is the least conducting in solution

• A. $K_2\left[PtC{l}_6\right]$
• B. $\left[Co\right(N{H}_3{)}_3\left(N{O}_2{)}_3\right]$
• C. $K_4\left[Fe\right(CN{)}_6]$
• D. $\left[Cu\right(N{H}_3{)}_4]S{O}_4$

Answer 1

The correct option is B $\left[Co\right(N{H}_3{)}_3\left(N{O}_2{)}_3\right]$

As it will not give any ions in solution
