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

A

`CsI `

B

`CsF`

C

`LiF`

D

`NaF`

Text Solution

Verified by Experts

The correct Answer is:
B
Amongst alkali metals cations (i.e., `Cs^(+) Li^(+) ,Na^(+)`)
`Cs^(+)` has the largest size and among halides i.e., `F^(-) ,I^(-) F^(-)` has the smallest size .Therefore ratio of `Cs^(+)` and `F^(-)` is the highest i.e., option (b) is correct .
