Single Choice

Among the following which one has the highest cation to anion size ratio ?

A$$CsI$$
B$$CsF$$
Correct Answer
C$$LiF$$
D$$NaF$$

Solution

The order of size of given cations is
$$Li^+ < Na^+ < Cs^+$$
and the order of the size of given anions is
$$I^- > F^-$$
Thus, when the cation is large and the anion is smallest, the cation to anion size ratio is maximum. Hence, cation to anion size ratio is maximum for $$CsF. $$
