A) 8
B) 6
C) 4
D) 2
Correct Answer: A
Solution :
Radius \[ratio=\frac{{{r}_{C{{a}^{2+}}}}}{{{r}^{F-}}}=\frac{100pm}{133pm}=0.75\] As,\[\text{0}\text{.73}\,\text{}\frac{{{\text{r}}_{\text{cation}}}}{{{\text{r}}_{\text{anion}}}}.\] So, coordination number of cation = 8You need to login to perform this action.
