A) \[276pm\]
B) \[138pm\]
C) \[552pm\]
D) \[415pm\]
Correct Answer: C
Solution :
\[NaCl\] has fee structure. In fee lattice \[{{r}^{+}}+{{r}^{-}}=\frac{a}{2}\] where a = edge length \[{{r}^{+}}=95pm\] \[{{r}^{-}}=181pm\] Edge length \[=2{{r}^{+}}+2{{r}^{-}}\] \[=(2\times 95+2\times 181)pm\] \[=190+362=552pm\]You need to login to perform this action.
