Question

Which among the following statements are true for the complex $ [Co{{(N{{H}_{3}})}_{6}}][Cr{{(CN)}_{6}}] $ ?
1. It is a non-electrolyte
2. The magnitude of the charge on each complex ion is $3$
3. The complex will not conduct current
4. The complex will exhibit coordination isomerism
5. The magnitude of the charge on each complex ion is 1

• A. $1$ and $4$
• B. $1$ and $2$
• C. $1$ and $3$
• D. $3$ and $5$
• E. $2$ and $4$

Answer 1

Answer: (E)

$ {{[Co{{(N{{H}_{3}})}_{6}}]}^{3+}}{{[Cr{{(CN)}_{6}}]}^{3-}} $
Coordination isomer of complex: $ {{[Cr{{(N{{H}_{3}})}_{6}}]}^{3+}}{{[Co{{(CN)}_{6}}]}^{3-}} $
