In the crystals of which of the following ionic compounds would you expect maximum distance between the centres of the cations and anion?

A

`LiF`

B

`CsF`

C

`CsI`

D

`LiI`

Text Solution

Verified by Experts

The correct Answer is:
C
As `Cs^(+)` ion has larger size than `Li^(+)` and `I^(-)` has larger size than F, therefore maximum distance between centres of cations and anions is in `CsI.`
