Question

Which of the following has highest conductivity in aqueous solution?

• A. $\left[Co\right(N{H}_3{)}_4]C{l}_3$
• B. $\left[Co\right(N{H}_3{)}_6]C{l}_2$
• C. $\left[Ni\right(CO{)}_4]$
• D. Cannot be predicted

Answer 1

The correct option is A $\left[Co\right(N{H}_3{)}_4]C{l}_3$

$\left[Co\right(N{H}_3{)}_6]C{l}_3$ is most conducting since it produces the most number of ions in solution.
