A) Csl
B) CsF
C) LiF
D) NaF
Correct Answer: D
Solution :
The order of size of given cations is \[L{{i}^{+}}<N{{a}^{+}}<C{{s}^{+}}\]and the order of size of given anions is \[{{I}^{-}}>{{F}^{-}}\]Thus, when the cation is largest and anion is smallest, the cation to anion size ratio is maximum. Hence, cation to anion size ratio is maximum for CsF.You need to login to perform this action.
