Solid State Question 263
Question: LiCl has NaCl type structure with edge length 512 pm. Assuming that the $ L{{i}^{+}} $ ion is small enough that the chloride ions are in contact, then radius of $ C{{I}^{-}} $ ion is
Options:
A) 223 pm
B) 224 pm
C) 181 pm
D) 362 pm
Show Answer
Answer:
Correct Answer: D
Solution:
[d] $ \sqrt{2a}=4{r _{C{{I}^{-}}}} $
$ 4{r _{C{{I}^{-}}}}=\frac{a\sqrt{2}}{4}=\frac{a}{2\sqrt{2}}=\frac{512}{2\sqrt{2}}=361.8pm\cong 362pm $
