Question

The limiting radius ratio of the complex $\left[Ni\right(CN{)}_4{]}^2$ is:

• A. 0.225 -0.414
• B. 0.414 -0.732
• C. 0.155 -0.225
• D. none of the above

Answer 1

Answer: (B)

0.414 -0.732

$\left[Ni\right(CN{)}_4{]}^2$ is a square planar complex whose crystal will be of octahedral structure ($NaCl$ Type)

$\frac{r_{+}}{r_{-}}$ ranges from $[0.414$ to $0.732]$
