A) \[1.40\overset{\text{o}}{\mathop{\text{A}}}\,\]
B) \[1.06\overset{\text{o}}{\mathop{\text{A}}}\,\]
C) \[0.85\overset{\text{o}}{\mathop{\text{A}}}\,\]
D) \[1.60\overset{\text{o}}{\mathop{\text{A}}}\,\]
Correct Answer: C
Solution :
[c] \[Ionic\text{ }radii\,\propto \frac{1}{z}\] Thus, \[\frac{{{z}_{2}}}{{{z}_{1}}}\Rightarrow \frac{1.06}{(Ionic\,radii\,of\,L{{u}^{3+}})}=\frac{71}{57}\] \[\Rightarrow \] Ionic radii of \[L{{u}^{3+}}=0.85\overset{\text{o}}{\mathop{\text{A}}}\,\]
