1.	The arrangement of `X^(ɵ)` ions around `A^(o+)` ion in solid `AX` is given in the figure (not drawn to scale). If the radius of `X^(ɵ)` is `250 pm`, the radius of `A^(o+)` is A. 104 pmB. 125 pmC. 183 pmD. 57 pm
Answer» Correct Answer - A Cation in octahedral voids `(r^(+))/(r^(-))=0.414` (without distortion), `(r^(+))/(250)=0.414` `r^(+)=0.414 250 =103.5 =104` (approx)
