A) \[100\text{ }pm\]
B) \[\text{125 }pm\]
C) \[\text{250 }pm\]
D) \[\text{325 }pm\]
Correct Answer: B
Solution :
For \[NaCl\] type structure, Distance between \[{{A}^{+}}\] and \[{{B}^{-}}\] \[=\frac{1}{2}\times \] edge length \[=\frac{1}{2}\times 400=200\,pm\] \[\because \] Radius of cation \[=75\text{ }pm\] \[\therefore \] Radius of anion \[=200-75\] \[=125\,PM\]You need to login to perform this action.
