Which of the following having having their radius ratio between`0.414` and `0.732`, i.e., for `NaCl` structure, have their radius ratio not in this range but posses `NaCl`-type structure?A. LiBrB. KClC. RbClD. BaO

Answer» Correct Answer - A::B::C::D
For `NaCl, r_(o+)//r_(ɵ) = 0.414 - 0.732`
But radius ratio for `LiBr, KCl, RbCl`, nd `BaO` are `0.34, 0.38, 0.77` and `0.83`, respectively, which are not in the range of `0.414 - 0.732`.
