A) \[0.137nm\]
B) \[0.241nm\]
C) \[0.274nm\]
D) \[0.482nm\]
Correct Answer: B
Solution :
[b] Solid AB crystallizes as \[NaCl\] structure, so it has coordination number 6 and its \[{{r}^{+}}/{{r}^{-}}\] ranges from \[0.414-0.732\]. For maximum radius of anion, we have to take the lower limit of the range \[0.414-0.732\]. So, \[~\frac{{{r}^{+}}}{{{r}^{-}}}=0.414\] \[\Rightarrow {{r}^{-}}=\frac{0.100}{0.414}nm=0.241nm\]You need to login to perform this action.
